Who are the people that control XMR? And how do they unfairly benefit?

XMR has nodes and miners that follow a set of consensus rules just like BTC does. It's not just another smart contract token with a pre-mine where the contract is loosely defined or able to be changed by a privileged few.

Montero can't be audited. That means it is fundamentally untrustworthy, because you can't verify the inflation peomises. Bitcoin fixed that already.

It can be. Please see XMR sub for how. 🙃

It CAN be audited. However, an inflation bug could exist without being detected. If an inflation bug was exploited in BTC it would be obvious.

As posted in a different comment, Monero uses cryptographic range-proofs to verify supply (nodes verify the range-proofs of each TX). In addition, a Python script to externally audit supply is under development: https://ccs.getmonero.org/proposals/monero-inflation-checker.html

Auditing that can't detect an inflation "bug" isn't auditing you can trust.

Agreed. I never hold XMR for more then a couple minutes so if I get debased in that time, it's an acceptable tradeoff for me.

Using a money like a hot potato because of its flaws does not bode well for that money's long term prospects.

Also agree. But it's currently the best choice for privacy as deemed by the markets where privacy is priority.

More darknet markets accept XMR than BTC. The good news is that these markets are always getting shut down and rebuilt so once BTC competes better on privacy, it should be adopted in short order.
