> What problem does FreeBSD solve by doing releases the way they do vs. the Linux approach of an LTS release with incremental updates
You're asking for what they do. 12.0, 13.0, and 14.0 are long term supported releases. X.Y where Y != 0 are incremental updates. A major version (X) is planned to be supported for 5 years, but specific minor versions (including the .0) have a shorter timeframe.
Most large changes are reserved for a .0 release, and .Y releases are smaller. Sometimes larger changes do get merged in though.
