I support and agree to everything you are saying. I love the community response. I too loathe the bug bounty asymmetry in power between corporations and reporters, but it exists.. by design. How do you imagine a researcher can 'demand' more money in this situation? They can choose the amounts arbitrarily and there is nothing legal or ethical you can do about it.
I haven't seen any proposals for real solutions - how would you ask this? How do you decide the amount for each company? Solutions, which do not bypass ethics or laws. I hope that 'the market' will solve this eventually and I think I at least raised awareness.
