Since it seems that neither that conspiracy nut blogger, nor Tash, not tvbcof, have actually read the paper they are all referencing and are just spewing their same word salad, allow me. Emphasis mine.
We found LINE-1 expression can be induced upon SARS-CoV-2 infection or cytokine exposure, suggesting a molecular mechanism responsible for SARS-CoV-2 retro-integration in patients.
This is consistent with the finding that nucleocapsid (N) RNA is the most abundant SARS-CoV-2 sub-genomic RNA, and thus is most likely to be a target for reverse transcription and integration
So we need a SARS-CoV-2 infection (and not vaccination) and the cytokine storm it causes (which you don't get with the vaccine) in order to reverse transcribe nucleocapsid RNA (which isn't in the vaccine).
So, all in all, another great argument for vaccination. Great work, detectives.
