Earlier quoted context omitted.
Homebrew was nice up until they packed it with spyware and then subsequently forced full tree clones† down the users' throats. It still might be useful for some people, but it certainly fell by the wayside. What a shame… †) As a result, Homebrew grew literally hundreds times larger and became unbearably sluggish. . PS: I'm wondering what drives some people to downvote this very comment… Stockholm syndrome maybe? ;P
People are probably downvoting it because in a scant few lines you manage to pack in two lies and a half-truth. It is not packed with spyware, it has not fallen by the wayside, and the full clone is due to a request from github to reduce the load caused by homebrew users (as in it is so popular that it caused a noticeable impact on github servers.)

[1] Regarding the forceful approach to unshallowing, they just chose the easiest way they could. You'd literally had to meddle with the code in order to accept shallow clones again. They didn't even bother to make a switch for advanced users.
