> the spread seems to be inflated (as they probably make money with it)

The Order Protection Rule of Regulation NMS makes this illegal (during regular trading hours).

Execution quality matters and given enough order flow a they can still match client orders to make a profit without giving a worse price than NBBO.

That's easier said than done. If you don't already have proper market making infrastructure and strategies you'll probably lose money trying to do that. Add in market makers paying per order and it doesn't make sense
