Ladybird is still very early in development and is not even targeting an alpha release until 2026. There are no binaries currently available, so the only way to even test what currently exists is to compile the source code. I am excited to see a new competitor, but I also do not have high hopes given how difficult it is to meet all of the web standards. Given the increasing number of websites that have problems or limitations with Firefox, I do not foresee Ladybird ever getting to the point where it could be reliably used by average people. I would love to eventually be proven wrong about this though.

Servo also has nothing to do with Mozilla anymore. It has been a part of the Linux Foundation since Mozilla laid off all of the developers in 2020.

This does not apply to the server. Only the client app is open source. The server is proprietary.

Whoever had the number before you likely gave it out to any service that asked.

Since you only use it for data, I recommend contacting your provider and asking for a different number.

Despite not being easy to find, most news sites still have RSS feeds. They are great for just getting the news from sources I trust instead of big tech algorithm recommend blogspam. It is also possible to get RSS feeds from subreddits and Mastodon.

Proton will still be a for-profit company that will be majority-controlled by a non-profit. The non-profit will not own all of the business either, so there will still be profits going to shareholders.

Which is the same structure that Proton is moving to.

Plus donations to Mozilla cannot even be used for Firefox development due to the structure of the foundation and corporation.

Graphene OS > iOS > Stock Android

The same is true for stock Android devices. Unless you are using a custom ROM without Google Play Services, there is more proprietary software than open source running on Android devices.
