Freedom from what? Good security practices? Open source does not equal security nor freedom. You’re pedaling digital politics instead of fact based privacy and security. Trust me I’d love my apps to be open source but ignoring blatant security issues is going to put someone at risk. You can’t have privacy without security and vice versa.
edit: like I mentioned previously, use obtainium and you can still use open source software
There is no completely free software, even if you take out the Intel ME (which is a very bad idea as it’ll leave you super vulnerable) The Intel chip will never be open source or FOSS at a hardware level. Even RISC-5 being open still has trust issues. Unless you setup a chip fab you’re at the helm of someone. And as the closed source hardware runs the open source software, is it really free?
