Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

Meat used to refer to any kind of food. Now it means animal flesh. Girl used to be a gender neutral term for any child.

Install in a smartphone context means "from the app store" now.

No amount of "here is an idea" hohoho sarcasm is going to reverse the flow of language.

No one's forbidding you from using the word install.

We have universal words like go, as in "go by foot" or "go by car" or "go by bus".

But we also have words like walk, run, drive, bus (as a verb), and Uber to specify how you go to a place.

And we can have words to specify how you install an app.

In my opinion, we're more likely to win by reclaiming sideloading (by giving it a positive connotation) or creating new words (and giving corpo installs a negative connotation) than we are to get current and future smartphone users to go back to using an older definition of the word install.
