>This goes for almost all software. 'entshittification' in software

It's really every category of commercial activity. Restaurants food quality, cable tv channels, movie sequels, home appliances, airline travel, theme parks, etc.

For years, I had a particular local HVAC company do my twice-a-year maintenance on my air conditioner and furnace. I liked the owner and he had a crew of older experienced guys that knew what they were doing. He then sold the business to another owner and he completely changed out the crew to kids that barely look 18 years old. The young inexperienced techs didn't have the skills to diagnose anything on their own. They always had to phone the home office and use their smartphones to send video/photos of what they're looking at to the more knowledgeable technician at the office. That way, the senior guy sitting at the desk can walk them through what to do next. That's when I realized the financial game the new owner was playing: hire new kids that just completed their 3-month HVAC tech certificate for cheap wages but still charge the same high prices that the old owner was charging for experienced techs. And only pay for one expensive senior tech back at the office to be a "shared resource" for all the clueless techs out in the field. That type of "enshittification" didn't require venture capital, or private equity, or ads. The common pattern of degrading a product or service has the same thing in common ... humans.

The vast majority of enshittification is not caused by private equity or ads.

Enshitification is a problem when the power structures are not in the user's favour.
