For most people this will have no effect because most people arent high profile enough to even have non-competes in their employment contract. I dont have a non-compete in my employment despite knowing all the numbers, which I can technically bolt and spill the beans to any competitor. But in finance, for whatever reason we dont have that. Even the VP doesn't because they bolt from peer company to peer company too. So for anyone in a non-compete it must be some ultra exec level job or you do some really secret shit that is so important it can sink the company.
No more non-competes is god for workers, but bad for companies. Now that guy can get hired, leave after 6 months and take his confidential info to a new company. Lets face it, people have loose lips. I've seen people show us sheets from their old company. They are not maliciously doing it. But they are like... "here's some cool reporting stuff from my last place.... oh just ignore the numbers". Well, the numbers they are pretty who cares so no big deal. But for any confidential info, non-competes are lets say two years long, so as time goes the possible downsides get smaller as the info can be outdated.
Only people with highly sensitive info(?) will be getting non-competes unless it's a weird company that blankets it to even an entry level accounts payables clerk. Companies will be more weary hiring people I'd guess because they now any new hire who would go under non-compete might bolt shortly after.
