You cannot renew a patent in the US. They get a new product patented, but anyone is still free to come along and make the older one. However, I bet there is a ton of expertise and cost required with doing that, and that is what is stopping others.

they "renew" by "improving" their existing product enough to make it obsolete, and to get a new patent. Per the article below this has been happening since 1923

That is better described as a new patent. The product for the patent that expired is expired, and can be made by others.
