This is a remarkably-astute comment. The problem is that it is very difficult for people to be aware, in any given moment, that a seemingly-innocuous action they're taking now will have devastating consequences in a decade or a century or more. This is made more difficult by well-heeled commercial interests which are highly motivated to discourage such insight. Ultimately, one of the roles of government, and it seems strange to say this, is to develop laws which paternalistically protect people from themselves. As an example of this, see privacy/data protection legislation for the internet, e.g. GDPR. As a counter example, see any country which very deliberately avoids developing privacy legislation for the internet.
The idea of being a "responsible consumer" at most just delays the inevitable shutdown for a few years, because economies of scale is a real thing. Moralizing to people that they need to spend more money / time / convenience / change their habits isn't effective, because even if consumers are genuinely interested in making sacrifices in exchange for quality, everything that's independent is closing anyway when the small owners sell out to whoever is buying. Those who thrive on mergers and acquisition don't care whether consumers are "responsible".
Consumers aren't children or robots, but we also don't have any choice or agency.. in the US at least there are 4-5 companies that make 80% of the groceries you buy. Telecommunications and media are going to look even worse, depending on how you want to measure it. As much as I hate to say it, it looks like only big government can protect us from big business. So yes, blaming big tech is missing the point, but so is blaming consumers. Write your congressman I guess? Wish I could write his economist instead though.. for whatever reason discouraging monopolies doesn't seem to work, so maybe we should look instead at deliberately incentivizing variety.
I get that online publications have to advertise, but to do it with auto-play video w/ audio of unrelated content, animated/video ads, ads for items you already bought a month ago, the outright scam ads, SEO garbage ("this one trick to get a supermodel girlfriend"), superstitials blocking content, dark pattern ads (e.g. x icon opens a link rather than closes the ad), ads that move and hover on the page when you scroll down.
I could go on for longer, but I'm getting that same negative physical reaction by simply describing this crap.
