Certain companies dominate Bitcoin.... In what sense. Bitcoin is a public ledger no one can stop you from using it, and the otherside of that is, we can't stop anyone from using it. If their tx follow CURRENT rule set it's valid.

People are currently using Bitcoin to scam people out of sats(ordinals).

So tx fees are kinda high, nothing compared to some recent times, but elevated none the less.

I'm still kinda confused. Are you saying what's stopping companies from pushing their bias onto Bitcoin?
