Defending the base

I can't say for certain why everyone might not seem concerned with protecting the base, but from my standpoint if I'm looking to get a certain number of Vanquishes for a Quest or if I want to pick up a good chunk of coins at the end of the session I will work to keep the opposing Team from capturing until they are almost out of time and then let up a little bit on the defense just so that the game can be extended until we get towards the back end of the battleground where you need to clamp down on the defense to secure the Win for your side.

I'm sure a bunch of other players do pretty much the same in order to enjoy a longer game period or to ensure getting a bigger stack of coins at the end, but I've also noticed that there are some who treat Turf Takeover as just a version of Team Vanquish with a map that expands and who don't particularly care about defending or capturing the Base.
