Why Prusa is floundering, and how you can avoid their fate
There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.
Klipper by contrast is a breeze to read through[2].
I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

E steps way off.
I think you are mistaken. I can't speak for implementations preceding the Ender 3 V2, so what you're saying may have been true at some point for other machines. However, here you can see Marlin developers confirm that there is an EEPROM on the stock E2V2 board using diagrams from Creality and photographic confirmation. Here is the datasheet for the EEPROM. Here is a thread discussing this Marlin release, and also the then-recent release of official Creality firmware which resolved the same issue. Since the stock firmware is based on Marlin, and at the time Marlin did not support this type of EEPROM, the EEPROM was not usable at launch. Any mainstream firmware (official or third-party) from the last three years will be using the onboard EEPROM unless the user intentionally specified otherwise.

Ender 3 Pro + Octoprint = Thermal Malfunction, system stopped! Heater_ID: E0
Also, checked the following discussion but seems like I need to update the firmware to be able to comment that like right? Temperature variance monitor tweaks by zeleps · Pull Request #23571 · MarlinFirmware/Marlin · GitHub

Anycubic Kobra Marlin 2.1+ based custom firmware
i spent some time and successfully rebased Kobra 2.8.2 OG firmware from an unknown Marlin ~2.0.8 frankenstein to a clean latest (as of now) release (not bugfix) 2.1.x -- v2.1.2.1 + 1 commit

Digraphs and Trigraphs
As an example, check the macropocalypse in Marlin - but the actual trigger for me to start was Reprap firmware doing a floating point divide in interrupt context while targeting AVR8 core…

Need advice on intermittent thermal runaway (Ender 3 V2)
Any change of thermistor or to a PT100/PT1000 will require recompiling the firmware, because every type has different characteristics. Marlin uses an internal table to calculate the temperature for whatever reading it gets from the CPU's analogue-to-digital converter. It has many tables for different thermistors, but only one is ever incorporated at compile time. So you have to specify which type you're using. You can see the commonly-used types in the list in Marlin's Configuration.h file, in the section headed // @section temperature. The tables themselves are in Marlin/src/module/thermistor.

Has anyone actually edited Marlin source code and added a new feature?
FWIW It IS open source but the GNU General Public License v3.0 rules apply. https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.1.x/LICENSE

Is it possible to delete the boot loader on a SKR 3 EZ?
Take a look at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader -- it may help. It's not only for the larger boards.

SKR 3 EZ Bootloader FW
However, I couldn't manage to find the original bootloader for this chip. I found this : https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which is very interesting for many older BTT controllers, but not the SKR 3 EZ.

Upgrade fw without sdcard ?!
The only other way is to use a little programmer such as an ST-Link, which looks similar to but is different from the little USBasp programmers that can be used for 8-bit boards. An ST-Link can flash firmware directly, but it's not as simple as using the SD card. See, for example, https://www.youtube.com/watch?v=7O_ZOdnM0SU and https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader

My micro sd card reader on my btt seems to be broken can I use a usb isp to update the firmware instead?
For LPC based boards this may help. It seems to allow flash over USB.

SKR Mini E3 v2.0 doesn't update its firmware even if the firmware.bin change to firmware.cur
It doesn't sound like an EEPROM fault, because that only affects various settings, not what functions and codes it supports. It sounds like something is wrong with the bootloader, eg it's reading the firmware file but not storing it. If nothing else works, is it worth getting a little STLink in-system programmer and reinstalling the bootloader and firmware completely? There's a link at https://github.com/GadgetAngel/BTT_SKR_13_14_14T_SD-DFU-Bootloader which should be helpful if you want to try that.

I think I bricked my skr 1.4 turbo
(If all else fails, you can try reflashing the bootloader - something on this page may help you.)

SKR V1.4T AGAIN!
Technically, it's possible to use a programmer to update the firmware, and I've seen descriptions of how to do that with various small programmers. Here's an example. Perhaps a google search will find more information, given that it does exist. People have used that technique to read and (re)load bootloaders and firmware.
