Security is a tradeoff (fucking always...)

It's the same reason I choose to keep my front door unlocked basically all the time - I know my neighborhood, the risk is really low and the convenience is high.

Further... practically everyone agrees that they don't need bank vaults as front doors. It makes zero practical sense: The cost is incredibly high, and the convenience is very low.

There are ALL sorts of wonderfully cool things you can do on a system where applications are allowed to trust each other, and the system is permissive by default.

You can customize behavior more easily, you can extend software more easily, you can add incredibly detailed & functional accessibility support, you can create incredibly powerful macros and commands.

This is so important that fundamental OS design from the early 90s actually prioritized and catered to exactly this style of open, trusted, platform (ex - all of COM in windows...). This is what made personal computing a reality...

All of those fall flat when you try to impose "well funded" security efforts.

Those efforts have a place, in the same way that bank vaults have a place. Whether that place is a personal computer is a different question.

Implying those folks are hostile for no reason is... at best a woeful misunderstanding of the situation, and at worst a malicious mischaracterization.
