Because it would be sponsored by anthropic/google/openai? You cannot do it (typically) without paying for the tokens they only can offer. Programming used to be free, but slowly, we need to pay for every single line of code. It's sickening
Nobody has taken away the freedom to program like we used to. Punch cards may be more expensive now, but vim and emacs are still as free as they ever were.
