Viruses absolutely do get weaker overtime. A viral strain that is too deadly is not able to spread efficiently. If the host is killed they obviously cannot spread the virus. That's natural selection. More deadly strains die out, while weaker strains successfully propagate.
“ In early 2000, researchers discovered a small group of sex workers in Nairobi, Kenya who were estimated to have sexual contact with 60 to 70 HIV positive clients a year without signs of infection.[9] These sex workers were not found to have the delta mutation leading scientists to believe other factors could create a genetic resistance to HIV.[8] Researchers from Public Health Agency of Canada have identified 15 proteins unique to those virus-free sex workers.[10] Later, however some sex workers were discovered to have contracted the virus, leading Oxford University researcher Sarah Rowland-Jones to believe continual exposure is a requirement for maintaining immunity.[11]”
I’m not comparing aids to covid. Covid is a respiratory virus and aids attacks T cells. Respiratory viruses are always “weak” from the get go in that they don’t usually kill a whole lot (your flus, commons colds, SARS, MERS) and humans are very quick to adapt an immunity/resistance to them. The idea that these viruses got “weaker” so they could “multiply more” is so fucking stupid it blows my mind. It’s literally the only organism without a brain, how the fuck do you think it knows to slow down because the host is dying too fast lol Our bodies our adept at fighting respiratory viruses pretty fucking well because, well we need to breathe.
AIDS, polio, hepatitis, these all affect different organs and are much more likely to fuck you up than a respiratory virus. But not a single one of them ever got “weaker” they stay the same or mutate into something worse. Hell covid is technically the same family of virus that causes the common cold and sars. What’s the say it didn’t mutate from that? Oh wait, it did.
Edit; keep downvoting ass clowns lol I literally have a degree in this shit

Bubonic plague and Ebola have entered the chat. Lol like did you wipe your ass and your comment showed up on the toilet paper?
The bubonic plague was a problem when people's idea of hygiene was to shit in a bucket and toss it out of the window.
Ebola was contained in a few areas in Africa.
u/Vivadiscordia is right and your examples don't disprove what he said.
K rabies. Explain rabies.
Lol I can go all day
Fine. Explain chicken pox
Chicken pox doesn't kill its host usually, so what's your point?
Uhh the flu literally mutates stronger every year.
Meningitis will fuck your shit up
Hepatitis also entered the chat.
AIDS turned into super aids.
I mean lol literally name me one fucking virus that’s ever gotten “weaker”
