I would wager they're cheering, because this builds the moat they don't otherwise have. Want to do business in America? Get government-approved. Can't afford the regulatory fees, or your government won't let you submit to foreign programs? Good luck!

Yes, this has been a steady play from the start. From the skynet fears, to the safety fears, now the it's to powerful fears. All of these have been a play to get the government to lock out any smaller or foreign competitors and build a moat where there otherwise would be none.
