And now they're one of the major backers. All the work is being done in the open, so it's not like there's a nefarious hidden agenda there (an agenda that would have needed to somehow stay dormant for 10+ years).
The idea that working for Microsoft is something dirty that should be shunned for open source just doesn't make practical sense.
And embrace and extend can exist in OSS models.
Microsoft is dirty, and it is dirt they cannot wash off in a mere few years.
If they behave correctly for 20 years, as long as they behaved in a literally evil fashion, then maybe they have reformed.
Just a reminder holding grudges isn't good for your mental health.
Microsoft has done many terrible things. Most companies of that size have. But they have also done a ton of good things. It’s impossible to take a group of tens of thousands of humans and not find rampant examples of both good and terrible things.
Sometimes one outweighs the other and that may sound like where you are but there is a wide gap between doing evil and saving lives, and most of us live somewhere in that gap.
