Depends on how strong a moat really is, but it can be "enshittify and lose", too. Enlightened (as opposed to short-term) self-interest may pay off after two years or twenty, depending, and in the latter case, it may as well not pay off at all as far as a public company are concerned.
I think Microsoft’s home game is “monopolize and enshittify”. They are the masters and know the exactly what amount of enshittification is too much. E.g. Hashimoto quitting GH is probably totally worth the 10 SREs they fired. Us plebs cannot go anywhere.
