    I don't agree that PrusaSlicer should've been closed source. Would PrusaSlicer be so good if it didn't have so many open source contributors? I think not. Prusa was able to leverage community development capacity and can then focus more on the overall printing experience, and I think they have mostly done that. Prusa is in the business of selling hardware, not software.

    Funny you say they "don't care". How do you think they prioritize your seams request vs other features? They are probably 4-5 engineers working on PrusaSlicer. The original issue that you commented on (https://github.com/prusa3d/PrusaSlicer/issues/9468) is dated Jan 31st, and has 14 comments. Majority of those by the same people. Compare that to 3,087 open issues on a free open source software. 72 open issues (not counting your "issue" which is just you ranting) just mentioning "seams".

    Since a few people were asking, here are my own prusa settings that I used to print the benchy in my previous post: https://imgur.com/a/NOv4oDp. For those of you that want to switch, you can download the latest release located here which includes default profiles for the 3 pro/plus/max models.

    It wasn't a big deal to me until a couple months ago when I needed to fix an issue with PrusaSlicer, and was able to fix it myself. If Bambu's slicer is based on Slic3r or PrusaSlicer, then it has the same bug, not fixed yet, and critical for those of us who need true multi-material printing at different material temperatures, but I wouldn't be able to fix it if their code is closed to me.
