Is there 1 FAANG company that is the most friendly/accomodating to someone who wants to develop their own software/indiegames on the side?
Our vacation also doesn't expire and we also don't have non-compete clauses.

"Participation in an open source community project, whether maintained by the Company or by another commercial or non-commercial entity or organization, does not constitute a conflict of interest even where you may make a determination in the interest of the project that is adverse to the Company’s interests."
A lot of employees were concerned about losing this after the IBM acquisition, but the former CEO made a lot of promises to us especially to protecting our autonomy, and (so far) IBM has kept those commitments to us.
I cannot imagine a more open source friendly place to work. I'm constantly surprised by how other companies operate open source projects or treat their employees who want to contribute to them (at work or otherwise). Unfortunately as Red Hat gets larger, we hire more people without that love of open source and they want to do things differently, but thankfully they don't get much traction.
I've found, as long as you're not making money no one cares what you're doing. As soon as money starts coming in, a lot of people are very interested in what you're doing. My totally uninformed guess would be that one of the first questions Netflix (or really any company) has about your off-company-time product is 1) does it make money and 2) how much. The answers to those questions will determine how the conversation goes from there, and how many lawyers are involved.
If you want to release it as open source and don't care about owning the copyright, there's a process you can go through to release a new open source project. If you just want to send patches to an existing project, you can generally just do that, as long as the project has an approved open source license and is not on the (short) list of disallowed projects.
