For the first paragraph - The main argument here is for bitcoin node runners - and that assumes that you are running a node. And I think most node runners are comfortable with running bash one-liner. For the second - When you are running a node you usually also run local explorers connected to your node (e.g. mempool space is built in in most node packages, like Umbrel), in the same way there are ways to run ordinals explorer locally. The website that I shown is using it's own local bitcoin node to read from and if there is CSAM in inscriptions (nothing is preventing that), then that node also has CSAM and there is a chance that that clearnet website would show it, unless they implemented some strong system to do analysis and filtering of CSAM before it gets displayed. It's important to note that CSAM is utterly disgusting, but nothing in this discussion seems to be making any difference (or even being related to) to actually preventing child abuse.
