I wanted to test this DuckDuckGo browser and had to create firewall exceptions to improving.duckduckgo.com and staticcdn.duckduckgo.com just to be able to install it... I already had it blocked because sometimes I use duck.ai and the connection to those domains serves no purpose to the service, and I had already opt-out of the "anonymized" telemetry, so I don't know why I was still connecting to improving.duckduckgo.com... off to a bad start.

I'm glad installers don't work on Linux

It's also incredibly annoying for file hashing and trying to verify the integrity and that the file wasn't tampered with or replaced in transit because often every single one of these stub online installers has a different hash because they're embedding time or some other variable about you in installer.
