uMatrix is more granular (and allows images and css by default) but still block the whole domain. They're in the business of tracking people so it makes sense. Whitelisting eng.localytics.com while still blacklisting all other *.localytics.com is another possibility.

Not really. Why waste time blocking specific scripts when the whole point of the company is to be sleazy?

There's really never a situation where I want to download something from a site like that, because I don't trust them at all and I completely disagree with what they are doing.

It's not worth whitelisting - I can read something else.
