I feel like anti-monoploy law should be used to prevent this kind of bundle selling. And this is something that is actually easy to implement. And microsoft will still do well. The smaller competitors get equal footing. Microsoft's valuation and competitive moat will not change too much. Not to the point where it's not survivable.
And when microsoft bundles everything. It forces things like Slack bought out by salesforce happening. ISVs like slack can't compete on it's own, it also needs another ecosystem or bundling to survive. So it forces ISVs to be merged into other ecosystems and bundles and it create big companies each with their own bundles. For the consumers, it reduces choice, create more lock-in, and less freedom to be mobile between products. From economic standpoint, it creates a few big businesses that controls a lot of things and makes so much money they don't even know what to do with that money.
