I never said anything about public ATM footage in Telegram, the stuff you quoted is in response to the Admin and the hosting question. Most people, including myself, do not self-host for a bunch of reasons, it is cheaper and easier to upload your stuff into the cloud such as Telegram or Google Drive. My initial statement was that most providers, use and rely on third-party infrastructure and that externals could duplicate it, on their own, or they could be forced and that no one could find out. My statement regarding cheap and Telegram as an example was to show that people upload everything into the cloud, which is also the case, Google Drive and other services is full of Material, all sorts of material. Other services exist but they make maybe compared to big providers 10 percent of the traffic.

Most I know uses Google, AWS or Azure. Because they measure CPU work time, not even storage itself. That is how cheap they are. They are reliable, they are cheap as hell. If you want to build your own infrastructure like e.g. The-EYE did to host Terabytes of data you constantly need to upgrade, which is expensive. Oh well, and they went down because of what... money. The benefit is also that you do not need to worry, you pay for not only the provided services itself, also they take care of security issues etc. If you self-host you need to take care of all of that and upgrading the software alone is often not enough.

I rather trust experts who do this professional than some random dude who hosts his mini server that can be taken down without breaking a sweat. I tried that myself btw, for example I created a Tor server, it was not even public, took 2 hours until I got the first attack and it never stopped ever since then until I took it offline.

Your argumentation that we never do this or that is absolute redundant, assuming someone would do shady stuff with footage, no one would admit this anyway or he simply would be forced by contracts to never talk about such specific deals. However, it does not change anything regarding my statement that, if they can, they never delete things. Most people only delete stuff if they run out of storage, but typical scenario is run and forget it... until there are problems.
