It’s about it being annoying or not. Microsoft is in a market position where they can leverage their different departments to heavily upsell you on other services. They have an unfair advantage that shifts the entire market to their favor, thus making it hard for any competitor to keep up or even enter the market.

E.g. they use every service / product they have to integrate Bing, they artificially limit the use of their chat bot to Microsoft Edge, they show Bing advertisements when you visit their competitors sites, they allow you to use Teams for free under certain conditions (if you already bought other products), they use their foot in the door with Microsoft Office / Windows go upsell you on Azure, …, Game Pass, …

I can go on and on. Some of them aren’t necessarily bad on their own. Some are. It paints a pattern of what Microsoft used to be. They actively used their position to try and create market conditions that would break their competitors or make it at least hard for them to even compete. About 15 years ago a lot of folks believed Microsoft had changed and were playing fair (in certain bounds), they invested a lot into open source and were generally a more friendly company. What we are currently witnessing is them going back to their old ways of doing things. Slowly tying everything back together. Probably under the assumption that this time the governments are sleeping and not really regulating it anymore. A lot of that is happening in the somewhat non-regulated cloud market anyways.
