there are lots of more constructive ways that the time and effort could be spent that could maybe even help other people too. for example if you look at tech support forums there are always people trying to recover their lost wallets. the effort could be put into improving the open source recovery tools currently available. and they do need a lot of improvement.
i doubt people who are trying to bruteforce addresses/pubkeys are capable of doing that though. most of them look for a compiled thing to run without understanding it.
