FlyGarmin is already back up. And it’s not a huge deal in my opinion. In addition to being only smaller operators, dbs don’t expire and roll over on the same day. New releases are available early.
Absolute worst case, if you were flying IFR and it was worth the expense, you could go to Jeppesen and buy a 1-off update for your avionics. Garmin Pilot could be replaced by a ForeFlight trial, etc. It’s not like Garmin goes down, planes are grounded.
