And if you bootstrap, you lose freedom in other ways. What kinds of businesses can be bootstrapped constrains your options. The market becomes your boss, and no amount of soft-skills or convincing arguments can change its mind.
Put that way, with investors you can say "At least my bosses are human"
(Note, I'm not saying one is better than the other in all cases, just that "bootstrapping gives you ultimate freedom" isn't true)
This. Once you accept funding, you're working for the money people.
Forget those narratives of heroic freedom. Your situation isn't really all that different to any other corporate environment.
If the money doesn't like you as a founder, you can lose your job (at best) or be back-stabbed out (at worst.)
And if the project isn't viable, it dies anyway. So you're still out of a job.
There's a cultural difference, in that you have more agency at the start. But the script you follow is already written by the surrounding financial culture.
You have no freedom at all to deviate from it - unless you bootstrap.
