When I bought my Commodore 64, you had to be a programmer to even use it...
I guess it must have really changed between the time you bought yours and when I got mine. All I had to do was put in a floppy disk and type a couple commands, and I could start playing games.
Although then every single tax jurisdiction - city, county, state, and federal - must have a different ad.
State and local taxes, being a "charge... mandated by a government", are specifically exempt from the rule. The average person is aware that advertised prices don't include sales tax and, perhaps more importantly, a person can find out from a different source (e.g. the government) what the sales tax is, so there won't be surprising extra charges.
It's a great way for idiots to advertise their stupidity. I can't wait to see who will admit to having critical systems depending on a tools which were formally depreciated almost a decade ago. If you depend on Powershell 2.0 (depreciated in 2017)...
So is not knowing the difference between "depreciate" and "deprecate".
Money is the root of all wealth.
