Yesterday: RNA can never integrate with DNA. Impossible.
Nice strawman. It's been known for decades that endogenous retroviruses exist, and indeed, up to 7 or 8% of the entire human genome is derived from virus RNA or DNA. The argument has always been that the vaccine does not cause reverse transcription and integration, and indeed the study you are quoting only shows that integration can happen with COVID infection, not vaccination.
So if you don't want COVID integration in to your DNA, time to get vaccinated.
It's funny, how they switch between these 'alternative' views on COVID:
1) Just a flu, your immune system can kill it easy peasy - vaccine contains chips and / or modifies your genome and is not needed to kill the virus.
2) COVID = incredibly high-tech engineered bio-weapon, super dangerous stuff
And on vaccines:
1) Just get COVID, it's much safer and more natural way to get immunity and vaccine doesn't even give good immunity
2) Vaccination kills healthy people by the millions, never ever get the vaccination,
they use it for population control and suppression of the population
