"The Keto diet, at 20 to 30 carbs per day, is designed to put your body into ketosis and keep it there. Ketosis puts additional strain on the kidneys as they try to filter excess keytones. Staying in ketosis over long periods of time will damage the kidneys."

A lot of people make these kinds of claims but you'll usually find they don't have very good evidence for it. I'm not aware of any evidence that long term ketosis will damage the kidneys, and I'm aware of individuals who have been in ketosis for years with absolutely no damage.

What is the evidence for kidney damage?

I’ve been following a ketogenic way of eating for more than five years because of unmanageable T2D under a SAD way of eating. I’ll take an A1C routinely below 5 as a measure of success. On a sad note, I did lose my kidneys in a tragic boating accident a few years ago, along with my guns of course.

"Staying in ketosis over long periods of time will damage the kidneys."

I've been looking for some support for this idea that keto will damage the kidneys. It appears that it's mostly based on the mistaken idea that a keto diet is high in protein.
