This isn't some_one_, it's some_thing_. I share your sentiment when it comes to individuals but extending the same sympathy to a company, especially one the size of Facebook, doesn't make sense imo.
It's not a question of 'sympathy', it's a question of recognising the neutral fact that a company providing its code to you free of charge is not further obligated - irrespective of whether you happen to like or dislike that company - to spend what you deem to be an 'appropriate' amount on maintaining the free software they provide you.
(And, even if any of the foregoing made any sense, the notion that an 'appropriate' amount is somehow measured relative to the company's revenue, rather than the factual costs of maintaining the software, is disqualifyingly silly in its own right.)
This isn't some random small library. It is/was a library developed by a FAANG company that underpins a large part of the JS ecosystem that they were paying their full time employees to work on.
