There is most definitely room for improvement. Small example: a lot of games’ downloads nowadays contain all the voicelines in every language in high quality audio files. Pretty much nobody will ever play a game in multiple different languages.
Another one: games come with 4k-textures now. Only a small fraction of players actually use a 4k display. Those textures eat up a lot of space and most players dont get anything out of them.
I wouldnt use youtube without newpipe/ adblock either. When i am at somebody elses place, i am just baffled by the amount of trash google tries to ram down your eyes. And the more ads they serve, the more people will be done with it and either get premium or look for options to get rid of it.
Even though it seems like more and more website now lock out adblock-users, i am confident that eventually there will be a “next-gen” of adblocks, that in turn circuvent these lock outs
There was actually a german ad about this quite some time ago: a grandma did this, then called her grandson “i think i just deleted the internet”.
How the ad continued? No clue.
What it was advertising? No clue.
