It bothers me that people forget that Linux's success has significant help from a combination of external events:
- PC clones
- AT&T / BSD lawsuits
- Microsoft antitrust suits
- Microsoft and IBM infighting (OS/2 and "Nextgen" OS development)
- HURD languishing, but GNU had solid build tools and libraries.
Now look at the state of getting an "Open Source" phone. I'm reminded of internal memos that came out where Bill Gates was wanted to lock open source out of ACPI: https://www.osnews.com/story/17689/bill-gates-on-making-acpi-not-work-with-linux/
Big tech has a vested interest in keeping their stuff closed off and beyond the skills and time available to volunteers.
