Add to that that they've worked hard to sabotage the competition, especially Linux.

They invested millions in a company that then magically decided that they should sue various Linux vendors and users, claiming that Linux violated its intellectual property rights, which was known bullshit. The goal was to scare companies into using Microsoft and they succeeded.

Then there is their continuous EEE strategy, Embrace, Extend, Extinguish, taking sodtware standards, "extending" those with incompatible functionalities, ensuring users will depend on those and oh, look at that, the files only work with Microsoft? Now you gotta stick with us

They could have invested in actually making their own software better but as usual, its easier to invest in lying in advertising, or investing in sabotage than to do that.

Fuck Microsoft. If I'd see a Microsoft office on fire I wouldn't piss on it to put it out. Now that they're working hard to kill themselves, let them.
