WhatsApp data leak: 500M user records for sale
Signal uses SGX for remote attestation, which presumably lets the client verify that the code running on the server is a build of the OSS code and not a modified version. But I don't know the details or if this is reliable.
SGX and remote attestation described here:

WhatsApp data breach sees nearly 500 million user records up for sale
Signal does private contact discovery and the effort they've gone to to do this is quite impressive.

Types of Execution Environments, Attestation and SGX
TEEs have numerous privacy-enhancing applications that may benefit users. One of them is, as discussed earlier, private contact discovery; the Signal application uses a contact discovery service enhanced using Intel SGX, a TEE technology, to protect its users' privacy. A similar application of TEEs is performing malware analysis in a remote cloud service, so that the service may not identify users by the contents of their devices, such as the applications they have installed, especially important as 98.93% of users may be uniquely identified by the list of applications they have installed.

Twilio Incident: What Signal Users Need to Know
Signal (or, more accurately, one of its predecessors) used to use client-side private set intersection for contact discovery, but this scales poorly [1].
Now they use a solution based on Intel SGX and server-side trusted computing [2].

Mozilla names new CEO as it pivots to data privacy
That isn't alarmist, but almost all privacy features in Brave are already in Firefox as well. Looking at this page:
- Chromium customizations: Not necessary in Firefox
- Client-side encryption for Brave Sync: https://support.mozilla.org/en-US/kb/how-firefox-sync-keeps-...
- DeAMPing: I think AMP has been dead for a few years now
- Limiting network server calls: I think this is a bit tangential to privacy, limiting calls is generally good but it doesn't mean you're transmitting less information. Brave's post comparing different browsers' first startup network calls is from 2019, not sure how Firefox performs today.
- Query parameter filtering: https://firefox-source-docs.mozilla.org/toolkit/components/a...
- Better partitioning for better privacy: https://developer.mozilla.org/en-US/docs/Web/Privacy/State_P...
- Referrer policy improvements: https://blog.mozilla.org/security/2021/03/22/firefox-87-trim...
- Fine grained / temporary permissions API: This is nice, I don't think Firefox has this.
- Social media blocking: https://support.mozilla.org/en-US/kb/enhanced-tracking-prote...
- Bounce tracking protections: https://blog.mozilla.org/security/2020/08/04/firefox-79-incl...
- Limiting the life of Javascript: https://blog.mozilla.org/en/products/firefox/firefox-rolls-o.... Not explicitly mentioned but I believe Firefox does have this 7 day limit as well, in addition to other protections.
- Private windows with Tor: Firefox doesn't have built-in Tor integration, but the actual Tor Browser is built from Firefox.
I think Firefox also has one or two features that Brave does not, like Multi-Account Containers, and some paid services like https://relay.firefox.com/.

Mozilla Monitor Plus: automatically remove your personal info from data brokers
> In a sense, it sounds like the advice of the services is less subscribing to them than trying not to have a few e-mails that map to your personal identity.
Firefox Relay is a great way to do that :) https://relay.firefox.com
Integrating that with Monitor is pretty high on at least my personal wish list.

Ask HN: How can we help Firefox not to dissapear?
> In what ways has mozilla meaningfully dared to try and expand their revenue streams?
I think that Mozilla VPN is pretty nice. It's based on Mullvad VPN, so they seem to know their audience (given that Mullvad has a pretty okay reputation among many tech savvy or privacy conscious folks, a lot of which probably use something like Firefox as well): https://www.mozilla.org/en-US/products/vpn/
I guess there's also Firefox Relay, for those who might benefit from something like that: https://relay.firefox.com/
Not many other products to give them money for come to mind, though.

Ask HN: Streaming Player Replacement for Roku?
I've been dragging around a similar concern. My solution might be to use Mozilla's Relay for the email and Privacy.com for the credit card.
https://relay.firefox.com/
https://privacy.com/
That won't stop the data collection but it should mitigate how useful it is. Maybe?
