Experts don't want to 'gatekeep'. Experts have been producing FOSS for the benefits of everyone, and liberally answering questions on mailing lists, stack overflow etc for free.

Experts have been badly bitten by poorly written and badly architected software, lost their hairs trying to figure out bugs and poor design.

They recognize the first version of a piece of software is only a miniscule percentage of the work and majority of effort goes into maintenaning it for its lifetime.

They are viscerally horrified at a thousands of LoC codebase generated at the speed of GPU inference they are to be responsible for.
