Everything in the paper is a correlation, and correlations alone do not imply a causative relationship. Therefore, you can just as plausibly argue that the symptoms cited have nothing to do with covid. That said, there's no reason to believe that people with "long flu" (the control group) would be less likely to experience depression as a result of their lingering symptoms, but that is what is seen. And remember that depression and anxiety are more common than the other symptoms -- they're happening in the absence of other "long covid" symptoms in this cohort.
Does Covid cause depression and anxiety, or are depressed and anxious people more likely show up to the doctor seeking covid treatment? You can't tell from a study like this, but the latter is a simpler explanation, consistent with a radical, society-wide initiative that uprooted people's social structures during the study period.
Also, this:
> painful auto-immune induced symptoms are well-documented in post-covid patients.
Is not true. There is some speculation and self-reporting of symptoms, but it has not been "well documented", or documented at all.
