No. This is not how we build a better internet. You can try to say "These companies will be responsible, and about people." all you want. But if the fundamental structure is still a for-profit corporation with equity investors expecting a return then that will inevitably trump whatever public good these companies were supposed to have at heart.

The only way we can actually achieve a better internet and a better tech sector is by changing the fundamental structure of the companies that build it. That doesn't have to mean they don't make money, but it does mean that making a profit for investors cannot be part of it.

Non-profits funded by grants. Employee owned businesses funded by loans. These might actually change the dynamics. But investor owned, for-profit companies funded by venture capital will not. No matter how much we might wish it otherwise.
