Is it just me or has anyone else noticed the decline in freelancing platforms since the pandemic started?

It's not even because of the massive layoffs and influx of new talent. The problem, as I see it, is that companies now see work-from-home as such a normative thing that they do not understand the difference between an employee and a contractor. 90% of the jobs I see posted read more like something you would see on a typical job board, here's a few notable gems that I've come across in just the last 24 hours alone :

• "The ideal candidate for this position is someone who... "
• "Candidate should be able to work on remote computer"
• "If selected, would you be comfortable working on your personal laptop?"
• "Due to state laws, our employees must have proof of vaccination (for remote contractors in another country???)"
• "...join me on becoming a founding member in my start-up."
• "...join our dynamic team. As a lead developer..."

The other 10% simply want too much for too little return. There's no middle ground anymore. I used to bang out three to five small jobs per month in my specific niche (web component development). But now jobs like these are rarely even posted, and the ones I do find are either hammered with bids in the first hour, or my obvious expertise is ignored because the client thinks they know more than the guy who's been writing code for 30 years... Some of these posts just blow my mind, here are a few stand outs :

• "Build my website ... Salary start from $550/Month ... Bachelor’s degree in computer science required"
• "Continuous self-improvement and be aware of new technologies ... (tagged with WordPress)"
• "This is not a job position, rather an idea I would like to discuss..."
• "We are looking for someone interested in working with us long term and to become part of our team ... The first job you will get will be under a contract of 5$"
• "I'm a developer ... build me a portfolio site ... I could do it myself but don't have time"
• "What is a Full Stack Developer? (proceeds to describe my own career to me in layman's terms with no project goals...)"

There has always been a certain amount of cruft to sift through when looking for jobs to bid on, but this is getting ridiculous. How is a senior-level specialist supposed to survive in this ecosystem? I don't know... maybe I'm being too picky/critical/indignant... How do you folks feel about the current state of things?
