I don't think it's a knee-jerk reaction, though
Note that nobody's complaining about the Heron and I'm pretty much out on a limb in my critique of the Monitor (although I stand by that and I think once the novelty has worn off, we'll see I'm right)
We have been playing the game for a couple of years, after all. Gunnyfreak pretty much nailed it and gave it a special role, which is something ships need, while being fairly priced- as it is, if the price dropped to $8000, it's irrelevant, because money is largely irrelevant, if you're even halfway competent. If, in the future, money is much tighter and that extra $10K matters... I'm still not buying it, even if the price comes down to earth; if money matters, then buying a ship that may become a flying cinder if the LRM Gods decide it's time to die just won't make sense, unless there's literally nothing else to buy.
There are lots of better alternatives, if one is looking for a freighter, at or below that price point. If it held another 50 Cargo, it might be
vaguely competitive as a freighter that we'd drag into combat with the greatest reluctance (since it doesn't provide a flight deck or have drones), but as-is, no, not even with full OPs and the armor / hull buffs, since those make a lot of merely good ships great, whereas the Cerebus would just become vaguely competent
against zero-level Admirals. But once we have Admirals to compete against... well, that kind of pushes back the value of the buffs and all that, and the Cerebus becomes a weak link.
