You have good points there but I have to point out some points also that I am currently thinking.
Internet
Internet is a world wide web without ownership and control while there is constant battle of giants trying to control it either by large services and tracking it's users. You have giants like google with majority of the network that has turned into monopol machine. All information is being processed, search results are being filtered and bad marked content will never get the views. There are always options of being vigilante and use tor network or other smaller providers but the result is that there is just not many people around and you will be very limited.
What certain bad contents are you talking about and how google do categorize it. As far as I know they only disallow shady contents that contains viruses or pornographic which are not suitable for all ages.
Social media
Social media are great for staying in touch wether to your friends, fanbase or group of followers. But as you know content is extremely monitored and there is only that much that you can share. This pattern in the last years is clear indication of new advanced ads and owners making the most of it. But even when you move back in time when there was not much ad limitations it would still narrow your options. Check out youtube on example. In a year or two they went from wild west into fword, family friendy content. There have been some political censorships but I will not go into it because I don't want to speculate.
Just like google, of course Facebook has to monitor contents. You also have to understand that just like any other companies they have to follow certain rules that abides the law. You can't just expect someone posting a dead people or someone going for a live show fully naked (as I have pointed out those type of contents are not for all ages and is really necessary to filter out). Social media is being highly used for fake news and that is making the platform hazardous to its users.
Work and career
Job interview... Think twice what will you write in your resume, no beard, watch out for any tatto, rather make a bunch of lies and say that you have no weak points. People get screwed over so easy over some bullshit things they do or say online. I mean do I haveto say much about it, you already know how it goes on.
Ahm I am not sure yes it is still really existing in some work types. and I highly disagree on this habit from our society.
