Name-calling an opposing “they”
"They" is now a dirty word?
Sideload wasn't loaded language before Android OS and still isn't: it's a bogus, overreactive claim.
All of them are valid install methods. Developers will always need a way to load their experimental apps not yet suitable for release: they won't block the methods they need to do that.
Clear use cases for casual users exist for
- deterring them from installing software by bad actors that's known to be malicious
- verifying non-malicious software hasn't been modified possibly maliciously before installing it.
"They" are drama-queens, because despite legitimate use cases to address actual problems posing high-cost risks to users (even as Google turns out to be a shitty authority) & clear documentation that power users can still install any package they want, they choose to catastrophize.
