Personally, I spend ALOT of my free time lurking 4chan's /g/ "technology" board, 4chan's /ck/ cooking board, and a carefully curated list of my favorite food and technology related subreddits on Reddit. I personally consider my addictions to be quite healthy because I learn and absorb a tremendous amount of information from sites that focus more on "actual content that matters" and less on worshiping the same small group of narcissistic acquaintances that congregate on platforms where "disliking" content is frowned upon.
Sure there's a lot of stupid crap on 4chan and reddit is full of corporate and government shills, but the internet has grown SO MUCH lately that the signal to noise ratio isn't as bad as it was in the early 2000s. My only problem nowadays is that I don't have enough time in a day to read/watch/comment on all the important stuff I find on the net. Compare that to the early 2000's, when useful information on the internet was so scarce, that I had to use minesweeper in my highschool computer labs to pass the time.
I for one am happy at how much content there is on the internet now. If you're smart, you can curate your own nonstop stream of "useful" content without that much effort. Problem is that you have to reject content that is curated by big businesses like Facebook and Instagram and Twitter and program your own method of retrieving things that matter.
People will always complain about the exponential growth of information. Look at newspapers and the printing press. I'm sure that people reacted the same way towards pocket watches and newspapers as people nowadays are reacting to smartphones and social media. Some people just have addictive personalities in general, and will blame not being productive on whoever's in charge of "information" at any given moment.
