Can someone explain me what they mean with "support FB devs" here?

something like this, I think:

By blocking ads on Facebook, more people are on Facebook. This adds to the success of Facebook and the salaries of the developers of Facebook.

By just letting the ads through, it’ll then be up to each user whether to continue using that site. And presumably, many will then abandon Facebook.

@mdione @ublockorigin I am not sure but I read it this way:
As long as ublock origin is trying to block facebook and changes its code accordingly, facebook devs work on circumventing this. If ublock stops doing it, the facebook devs are not needed to circumvent unlocks measurements.
But not sure if this is meant, and my french is a bit rusty.
