There could be 3 out of 1000 people that make you feel not welcome. Don’t judge a platform because of those 3 people. Maybe it helps to focus on the 4 out of 1000 people that make you feel welcome. And don’t think about the 993 people who really don’t care what you write.
If that is your intention, GPL would make more sense, as every improvement and development would be forced to be made available to those people, thus helping them further.
I doubt that your code helps anyone who needs/deserves to be helped, after beeing processed by big corpo.
You could think about your definition of freedom. For me: My freedom ends, where it restricts others people freedom - I shouldn’t be free to rob people and call it restriction if someone forbids this.
