They created a product that serves a purpose, they should get rewarded for that. Their are 100% self custody options available.

By that logic, the fiat bankers also deserved to get filthy rich by exploiting others under the guise of providing a service.
You don't need to use a non-custodial wallet, it's that simple, there are other options. People can choose either, both or none. If you don't or can't self-custody then you can use these services, that work because they do, but it is your choice. Your not forced into it like the banks, banks suck for sure, bit for some things you might need a company with skills, the technology and money to build a product. Take cars, super useful and expensive, but very few people can build there own, therefore, there is no real choice. In wallets, self-custody vs non-custodial, there is choice.
Zeus is self custody, but still charging.
And there are still other options that don't, you just have to do all the hard work yourself.
I think we both agree that the banks, pharmaceutical companies etc are government protected cartels that control the market for massive profits. We can't lump smaller businesses in with them, in my opinion.
I would add that you have also the option to make your own. It has a free market. Bitcoin is open source, so everyone can learn their way in. The banking sector is not that straight forward.
For sure, another option. nostr:npub1nhzltwf8n6cjt0z4kes8qt82ashu32jnjz04k75p2uffy23f6d5s4c4wd0, do you have a wallet connected? Can't zap you.
