> I don’t have any experience building mobile apps because I didn’t want to buy into an unfair ecosystem

Seems like it wouldn't be much of a stretch to compare that statement to not starting a business because the economy is unfair. People indeed don't start businesses when the bureaucratic or tax overhead outweighs the financial benefit, but nobody loses sleep over an individual's hypothetical missed opportunity to learn a new skill but them. Doesn't matter to the platform owners unless it also stops being profitable, so it's their job to maintain the profitability for their ecosystem despite whatever barriers they put up.
