Not a problem for me (Unlimited data plan, 1000/40).
The website is around PC Gaming - users with the top of the line machines and fast internet. I don't see a problem with websites catering to their audience?
Why should I get a worse lower quality website full of text and nothing visual because somebody else has limited data?
By that logic, they should be pushing 500gb not 500mb, gamers with top of the line machines can afford it!
