Although I'm strongly against those intrusive ways of anti-piracy stuff which tries to fight illegality with ways that are virtually on the constant boundaries of illegality themselves, I can, in my personnal case (internet coonection 24/24 etc.), live with it.
However, if it makes SH5 too much of a hassle to mod, then SH5 loses 80% of interest to me, as i'm being an avid modder and usually start to try to mod the game not even after only a month of playing it
