Perhaps some overzealous reference to the fact that Graham Linehan is a massive wanker, butthurt transphobe. The way you "can't really make rape/racist/sexist/transphobic jokes anymore". He doesn't really make TV anymore. This skit on the other hand, as well as most of Father Ted and The IT Crowd, is perfectly PG.
I used to love this show until that one transphobic episode. After watching that I looked up the main show writer and learned that he is huge piece. Such disappointment.
The IT Crowd basically cemented itself as timeless by never directly referencing anything super techy that would date it. Sure, there's a guitar hero controller and an xbox 360 in a lot of shots, as well as some 4:3 laptops, but that's about it.
What you forgot to mention is that someone bought the original piracyisacrime.com domain as printed on your DVD. They made it redirect to The IT Crowd piracy scene :d
I prefer people posting the original source, and I'll just let LibRedirect (on desktop) or LibreTube (on mobile) switch the link to my preferred Piped instance. I don't want to use random instances.
I feel like most people who feel strongly against YouTube will have it set up similarly to where you automatically get redirected when clicking a link anyways. You can always offer up a Piped link in the text box or the comments as an alternative.
