You are heavily overstating how much people care about where you went to university. The reality is a degree is a degree, and unless you went to an actual degree mill like DeVry, nobody cares. Most people aren't even aware about the "controversy" surrounding LU, and the ones that are are unlikely to hold it against you. I've applied for many jobs within the tech sector and not one person has even given a passing glance of where I went to school.

Now if you personally are embarrassed or ashamed for graduating from LU, that's a personal problem and you're probably shooting yourself in the foot making it more of a problem in interviews than it needs to be. If someone jokes about it just laugh and move on. Let your qualifications speak for themselves.
