You really shouldn’t answer questions you clearly don’t know the answer to. There a dozens of ways for apps to report your license status. Most people just don’t know about it.
You can look at a MS Word doc someone sends you and detect the license. Apps can phone home all the time to report your status. Just because you’ve never noticed ot or no one ever caught you doesn’t mean there’s ‘no way’.
I honestly am baffled when people take time to type this type of crap out and post it. You clearly do not know, but you posted it anyway AS IF IT WAS FACT, despite it being provably false.
If you have two devs pair programming, at least one of them is being slowed tremendously. It should be used very sparingly and only in junior/senior mentoring attempts. Putting two senior devs on pair programming is nearly always just slashing your dev productivity.
I’ve seen devs take 3 days to write code in pair programming that either one could’ve completed on their own in 4 hours or so.
Or we could just work remotely, which is far more productive.
