One reason I can think of is the amount of capital required. So basically when Microsoft or Apple started out, you didn't need a lot of capital to build a minimum viable product. There were not many tech products.

Nowadays, it's it's obviously different. To come up with something innovative, you need to develop something for a longer time so that it's better than everything that's already out there.

Can't say I agree with this. Seems to me that it's never been easier, faster, or cheaper to make a useful tool or service. Obviously the world is a lot more competitive now, with a lot more people trying to make stuff. But a skilled developer could certainly make a project on the side while holding down a good job at a bigger company and release it independently and bootstrap it.
