I don't see anything above justifying your "scammy" word, which is libelous thrown without back-up and therefore does reflect badly on you. But please, go on: justify it. I'll help by citing the dictionary definition of "scam":
Noun: a dishonest scheme; a fraud.
"fraud": "wrongful or criminal deception intended to result in financial or personal gain."
Also, as the tweet I linked above said, we didn't profit from either the fast-fixed error of showing unverified creators as being tipable with our token grants to users (we don't make money recirculating our own grants) or the refgate case (we turned off that future-share-of-trading-commission affiliate revenue with Binance).
Hanlon's razor explains these blunders without jumping to scam or fraud, which is a crime we have to fight on the Brave Ads front, so I take it seriously.
Should someone not use Brave on account of these two mistakes? Not for me to say; no browser is perfect. But they were not scams or frauds, and we fixed code and design processes to avoid anything like them in the future.
