Every company that uses Cadence, etc. has somebody on staff who can "handle" the license server "issues", whether in the US or overseas.
The difference is that in the US enough licenses are used to pay for the "average" number of users, while overseas it's zero.
And frankly, if the big EDA tools companies actually fixed and improved their software instead of milking it for decades, legit US clients would care more than they do now.
For those who haven't had the pleasure, most EDA products are like buying a boxed Windows in 2021 and they turn out to actually be Win 3.1 - no exaggeration.
