This chart is entirely misleading. In any given year, there are only 85k new H1B visas. That's it, it has not grown nor shrunk.
Reason for increase in population shown here is H1B renewals. Normally the way this works is H1Bs convert to permanent residents, but due to the country caps, Indian/Chinese H1B holders keep renewing their visas contributing to this increase. Again these are people who are already here and got their approval sometime in the past, so its not like in 2022, companies collectively hired 685,117 (which is also why you see the decrease in 2023 since due to covid, a very little bit of backlog for residency cleared).
(Not to mention the sentiment of comments here is entirely disappointing, but I guess that's the vibe these days)
