Nobody will touch your product if it's not OSS doesn't mean you should call it OSS and then rug pull. Build it proprietary from the beginning you cowards. The people who do this are the same as the corporate shills who infiltrate subcultures to monetize them and ultimately destroy the community in the process. If you don't actually share the values of the community you're trying to join, then don't join it.
This little SV "growth hack" where the success of your OSS project is the proving ground to get funding has to die. It's turning a high-trust community into a low-trust one.
