I don't entirely agree with that. Up until IE6, MS made a
LOT of efforts towards making web apps work relatively well compared to alternatives. DHTML worked a lot better in IE5-6 than in the Mozilla counterpart at the time imho. It wasn't until around when Firefox (then firebird) came out that it started to really shift. IE was stagnant for what seemed like forever. IE7-8 were relatively insignificant shifts supporting some newer features, but still didn't resolve some of the huge memory holes with the JS engine and rendering engine separated by discrete COM layers. (separate issue)
I can agree with that in some regards, but I do think that MS has done a lot of things better. I think classic ASP was much better than PHP, though most of the unique functionality you might need was captured behind third party COM components. I think C# was/is a significant improvement over Java, and prefer .Net in general. .Net Core has been a very good shift, though some things seem more convoluted than they probably need to be.
As someone who tends to reach for Node first, I really do appreciate MS's efforts in that space to get things running as smoothly in windows as in Linux and Mac. As an early adopter (0.6/0.8 era) windows use was pretty painful. VS Code is imho was leaps and bounds ahead of brackets and atom at release. I also really do like MS Teams, though lack of a Linux build of the client is just stupid and short sighted.
I still use chrome first, but have ublock origin enabled, and tend to be picky about my exclusions, pisses me off to no end when sites just don't work with it enabled.
