RMS warned of this a bit over 20 years ago. This is why you should get Free and Open source software and not Open Source Software. Preferably with a GPL licence which allows you to download, run, read the code, modify it and share it. Open source can mean you only have the right to read the code and signal to the dev code you’ve saw that could have been better or errors you saw.

It’s Thunderbird… Of course they release the code! How would it even exist without releasing the code?

BTW: K-9 is also Thunderbird.

Paid builds. You get Access to the source code but you can either build yourself or pay a small amount to have a packaged built and updated whenever.

I also like the twice a year nag screen thunderbird or Wikipedia uses (KDE was right to start doing it too, in my books).

I don’t believe a small donate button in the “about” section of the settings screen is of any use.

I doubt it changed much and it sounds logical too.

Or morally better than breaking TOS, use a FOOS alternative like Jellyfin.

Pcloud will probably go this way.
