We just love to merge the internet into single points of failure

This is just how free markets work, on the internet with no "physical" limitations it is simply accelerated.

Left alone corporations to rival governments emerge, which are completely unaccountable. At least there is some accountability of governments to the people, depending on your flavour of government.

no one loves the need for CDNs other than maybe video streaming services.

the problem is, below a certain scale you can't operate anything on the internet these days without hiding behind a WAF/CDN combo... with the cut-off mark being "we can afford a 24/7 ops team". even if you run a small niche forum no one cares about, all it takes is one disgruntled donghead that you ban to ruin the fun - ddos attacks are cheap and easy to get these days.

and on top of that comes the shodan skiddie crowd. some 0day pops up, chances are high someone WILL try it out in less than 60 minutes. hell, look into any web server log, the amount of blind guessing attacks (e.g. /wp-admin/..., /system/login, /user/login) or path traversal attempts is insane.

CDN/WAFs are a natural and inevitable outcome of our governments and regulatory agencies not giving a shit about internet security and punishing bad actors.
