I may get tarred and feathered (well, more likely simply digitally snuffed out or whisked away to the digital concentration camp of shadow banning and/or digital gassing) for saying this here, but I think you are talking about two different motivations.
One is the VC/investor trap, where the primary unrealized motivation is actually just finding VCs that will fund some scheme to be the "next {insert hopes and dreams of boundless riches}", where far more often than not the winners are the cunning founders (Adam Neumann anyone?) and the VCs, with everyone else left holding the bag (Hello, WeWork starry eyed people that believed the predictions of alien visitation) if the effort can't be pawned off on someone else, or some "exit" to a corp in a kind of reverse defensive blackmail auction to snuff out or keep a competitive advantage from a competitor.
The other thing goin on here is that very predatory and pernicious and rent seeking nature you are directly referring to that seeks to constantly corral and rope in as many consumers as possible as the whole tech industry is rapacious in its lust to generate "ongoing revenue streams" through dependency or even (what used to be illegal) what amounts to predatory pricing and snuffing out alternatives by reaping havoc on the target industry and society. None of these tech companies should have been allowed to use this predatory pricing model to utterly decimate our economy as they have … Amazon, Uber, WeWork, etc. are just a few examples. At the very least it should not be allowed for public money (pensions, etc.) to be invested in companies that are unprofitable at certain ratios, e.g., over 1/4 of their existence.
One clear example comes to mind in Uber/Lyft and their wake of both immoral and illegal actions that have led to the utter collapse of the taxi industry through unfair competition, predatory pricing, and illegality. What we are now left with is a for-hire transportation sector that is now a far less competitive environment (Uber/Lyft compared to roughly 5-20+ taxi companies per city (Ignore the flaws of the industry that are irrelevant to the anti-competitive issue), but we are now also facing a collapse of competition on a far larger scale, essentially Uber/Lyft instead of literally tens of thousands of taxi companies just alone in the USA.
So what happens when the Taxis cannot keep up under the Uber/Lyft onslaught? Well, we know what happens, they use regulatory capture to limit and prevent competition and they start raising rates as they have and are doing.
