It is though!

Often news websites use the user agent to detect e.g. the google crawler, and allow google to index the contents of news articles; but then throw up a paywall when anyone with a normal browser shows up.

I recall some news websites tried to threaten people making browser extensions with the DMCA/CFAA as they considered it working around their copy protection to illegally gain access to their content.

Every browser pretends to be all the browsers before it to get around restrictions on who can see/render content.

Same as it's a feature of my filing cabinet that items don't incinerate themselves whenever I move house.

Signal doesn't let you migrate chat history to your desktop.

Trying to migrate between phones while retaining your Signal history is too hard for most people.

Signal is not at all a suitable replacement, and I believe that forward secrecy is an anti-feature for an email-like usecase.

e.g. historically anti-virus engines have had bugs where e.g. when they search inside of a .zip file; their .zip parser was susceptible to a buffer overflow that would have allowed a malicious file when scanned to run arbitrary code.

e.g. some anti-virus software has a daemon that runs on localhost with an exposed port. This port receives RPCs. websites in your browser have been able to make requests to the anti-virus daemon.
