The video's comment section is full of mindless criticisms. Commenters don't think that investing for very expensive camera gear is 'a great sin' for them.
For me, taping Linus Tech Tips, Techquickie and Channel Super Fun in 4320p60 and down-sampling and editing it in 2160p24 or 2160p30, is a very good idea for archiving it on archival-grade hard drives or magnetic data tapes that will keep their data for 30-100 years.
