I spoke to a commission of congressman about this topic. (they wanted to talk to small startups). It seems really difficult to effectively regulate this. - acquisitions are part of what make the startup ecosystem work. It's not at all clear which acquisitions you should block - the bundling approach that google uses makes things like android free - you dont want apps on iOS and android running their own payment infra…
That's such BS. A startup whose only business plan is to get acquired doesn't deserve to succeed in a competitive market. If that route becomes nonviable and a bunch of silicon valley startups go under, then good riddance.
The US economy needs startups with sustainable business practices and highly competitive products and services. Not acquihire schemes.
