Earlier quoted context omitted.
If we're going to be pedantic: No. Pulp fiction was fiction written for the popular pulp magazines of the 1900s through roughly the 1960s. Those magazines don't really exist anymore. The "modern equivalent of pulp fiction" -- which is to say, the modern equivalent of writing for the pulps, writing to earn a quick buck -- is self-publishing low-effort fare on Kindle Unlimited or something similar. So the guy you were…
The medium doesn't matter: it's metonymy, pars pro toto. Pulp fiction remains pulp fiction despite literal pulp's retirement.
As such there should be absolutely no issue with somebody saying "modern equivalent of pulp fiction" -- because they're using the first definition. And it so happens that there is a perfect modern equivalent, which is essentially the author in OP's publishing style.
