If anyone wants to debate whether sideloading is a neologism, take it up with Sandisk circa 2007 https://xdaforums.com/t/sandisk-announcement.316860/

You're free to search XDA Forum. 2007 was the earliest mention I saw, but conversation seems to start in earnest around 2009 and never stops. Consistent hits in search from the last TWENTY YEARS.

This is not new. It may be new to you but any scary and evil connotations are your own ignorance. The term has been in common use for decades.
