I'm... not sure what the point of this is.
The cynical take from that is that they can burn on non-profitable choices for far longer than your average competitor. Since, as you say, they can do this for a long time.
Note that this isn't really new, either. MS used to (still does?) give ridiculously reduced/free offerings to students, only to build an entrenched mindshare that "this is the way." Nor is this just MS. Fusion 360 recently made headlines by changing their "reduced" option. I recall for years it was open speculation that Adobe used to turn a massive blind eye to piracy, as long as it was growing the demand that shops have to use their product.
Now, I think a valid criticism of me on this, is that I don't have an alternative. I don't know how to really regulate the behavior I think should be the norm here. My pipe dream would be that they have to use open standards for data exchange. If you are trying to build a new foundation, it has to be one that either pays for itself, or has an exit that is not encumbered by vendor lockin.
