The ad-based internet is dying, and it's getting worse in the process [video]
His two examples are Twitter and Reddit whose ad revenue is dying because those two companies have made huge blunders. Elon seems to almost actively be killing Twitter (which the poster even states). Reddit screwed Apollo and then many of the most popular subreddits protested and did things like show porn on otherwise usually SFW content to prevent Reddit from showing ads and thus killing their profits. Those are big sites, but those are definitely attributable to other obvious confounding factors. I would definitely argue they should be the first data points thrown out in asking "is the ad biz on the internet dying?". I do think ads have gotten worse but I definitely don't think it's going anywhere for a long long time. Way too many companies have built their whole revenue model around them. And companies may spend less to post ads but they definitely still will because there really aren't that many alternatives.
