I find it a bit weird when people anthropomorphize corporations and feel bad for/protective of them.
And let's be honest, we're not talking about "mistakes", we're talking about a decades-long strategy which was methodically executed to cultivate good will, and then take advantage of it to destroy competitors.
The MS of today isn’t the MS of the 90s. That’s not to say they’re virtuous and wonderful today, just that banging on about the past doesn’t really feel relevant.
So, I just checked https://news.microsoft.com/leadership/. The vast majority of the people there joined Microsoft in the 80s or 90s. Two or three in the early 2000, and one after 2010. For one person it was unclear when they joined.
So, an overwhelming majority of the senior management were perfectly happy to work for the "MS of the 90s". Therefore, it's hard to see that they'd be particularly uncomfortable with the ethics of the "MS of the 90s".
Companies definitely have personalities and traits that last longer than their constituent members, that's what's called a culture. Just like a nation has defining features that will still be around when every single currently living member is dead, so have companies. In particular old, large ones.
That's not to say that they can't change, and Microsoft definitely has changed since the 90s, but the past is not irrelevant.
I see it as reminder to frequently check whether my opinions on different things are still valid.
This is why I disagree with your claim that Microsoft is giving away VSCode away for free to promote their own proprietary tools. You can shame Microsoft for trying to improve their image by making VSCode, Typescript, ... opensource. To me this is totally different from bundling your own Browser into an operating system to increase artificially your market share, you can't compare the two.
There is nothing bad about not blindly trusting a big corporation like Microsoft, but I dislike it when people are so desperate to blame Microsoft for mistakes it did in the past, that they write articles that are (deliberately?) misleading. In this case, by saying parts of VSCode are opensource when it is just some extensions. This is putting VSCode on a pedestal with Chrome, but the comparaison is all wrong, Chrome includes lots of proprietary parts, while chromium is the opensource variant you can build yourself, but for VSCode this is completely different as the version distributed on the Microsoft website doesn't include anything besides the opensource code from Github repository.
