Something similar to what you are describing is called hot metal forming where you heat up a metal tube ( like aluminum) and then pump it full of gas. I don’t have any experience with this method, I only learned about it theoretically, but some of the parts can get pretty complex.
It’s mainly used in aerospace, but I’ve also heard of it being used to make some HVAC stuff
I mean i get that matrix is used by bad people, but that doesn’t mean that matrix is bad.
Any decentralized platform will have this issue with csam, but that doesn’t make ot bad. Matrix is basically what TOR is to browsing the internet, people use TOR for CSAM but that doesn’t make tor bad.
However he does raise up a big concern and thats that homeserver admins are unable to change what they are hosting which means that they are forced to host CSAM which is a really big issue
Overall tho, matrix is still a good platform. There’s nothing wrong with government contracts, its all open source. TOR was developed by the us military but that doesn’t make it bad or even less effective
All of these things can change
