Scanning the Internet for Vulnerabilities

I would like to solicit the opinions of network operators on the practice of scanning all of, or large chunks of the internet for known vulnerabilities. In earlier times, this was generally viewed as being distinctly anti-social behavior, but perhaps attitudes have changed relative to earlier eras. I would thus like to know how people feel about it now, in 2022. Regards, rfg P.S. Just to be clear, I personally have neither any desire nor any intent to undertake such activity myself, nor am I in communiacation with any party or parties that have such an intent or desire. I cannot however say that I am unaware of any parties that may currently be involved in such activities.
