Every single financial institution on Wall Street, the City of London, Amsterdam, Tokyo, Dubai and so on, uses Python. Very few contribute.

I've worked at a few that use the 'mold' linker to dramatically reduce their build times. Again, very few contribute. In this particular case, I managed to get one former employer to make a donation.

But the list goes on.

Short arms, deep pockets, as the saying goes.

It’s interesting to see everyone advocate for open source software with permissive licenses, then get mad when companies use them.

If python wants to require money for updates or for customers over $X in revenue, they can!

If companies don’t want to donate, they don’t have to just as python contributors don’t have to if they’re annoyed at how it’s used.
