I wouldn't say it was Lemmy that has changed but it's been an integral part to a change in my lifestyle. I don't use Reddit anymore, I switched from Windows to Linux, Degoogled my phone, I take way more consideration into my privacy. All social media account but Lemmy are gone now. Cancelled my Amazon prime and all video services. I have blocked ads from everything in my life to the point that when I see one, it stands out like a sore thumb. I am far more aware of how companies manipulate customers in order to sell product.
