I have not watched the show but from reviews and summaries they seem to be.
You know, I had a teacher once who would
eviscerate students if they piped up with opinions on the books in discussion if it turned out they hadn't actually done the required reading. After all these years this comment reminded me of that, and illustrates where he was coming from.
Creating androids for manual labor, if not slavery, who later killed thousands of them and then 12 years later not knowing why they did so.
The Federation used obsolete mark 1 EMHs as manual labor in mines, because they did not see them as sentient. If anything, using humanoid AIs for labor is on brand for the Federation.
There's also the assumption that they were sentient, of which we were given no indication on screen that this was the case. For all we know the Federation.requested stops and securities in place to ensure sentience
doesn't develope. And if they weren't sentient, they certainly weren't "killed".
Also, who doesn't know "why they did so?" The Federation knows why they decommissioned and banned the synths. Because something went horribly wrong, people were killed, and they lost one of their oldest colonies and most important ship yards. We as the viewer know the androids acted as they did because they were clearly hacked/reprogrammed. And who did the hacking, why, and why would they go so far is the show's mystery which we are in the process of finding out.
Letting ex-Borgs be tortured and harvested for their implants.
That's like blaming the police for "letting" criminals do crime. Especially if the crime happens outside of their jurisdiction, or the criminals retreat there afterwards. You have to catch them to stop them, and people like Bjayzel operate in and retreat to the former Neutral Zone for the express purpose of lying low and being out of reach. It took Seven ages to find her, and basically by accident, and boy did she have incentive to look.
Maddox working with someone who tortured and harvested from ex-Borgs.
So, this is a clear case of didn't actually watch the thing we're complaining about. Maddox isn't working with her. He borrowed money and resources to continue his work that was now illegal in the Federation, and like any loan he's supposed to pay it back. There's
no indication he knows exactly what some of her unsavory dealings entail (he very likely wouldn't have come to her admitting he can't pay her back and that other people with a lot of money were looking for him if he had known about it).
Maddox's former colleague and Picard's current colleague, co-star of the show, killing Maddox.
Again, part of the mystery of the show. We don't know what's up with that yet.
Picard's former first officer being a drug addict.
How ... dare she? Sometimes people are maladjusted and fall through the cracks, and especially addiction is hard to overcome if the addict doesn't want help.
And having a character succumbing to drug addiction because of personal set backs is no more indication of "incompetence" by the Federation than Reginald Barclay is. You know, the hypochondriac with almost crippling anxiety and a holodeck addiction who we learned had been passed from ship to ship with untrue letters of recommendation and was in the process of being transferred from the Enterprise, too, in order to be someone else's problem before Picard stepped in?
