They will just use memcpy_s with the dest len and the len set to the same var. Or strncpy with the limit set to strlen(src) etc. These guys will tell you it's suddenly using 'modern security practices'.
Conversely depending on the code strcpy / memcpy can be 100% safe.
I think these guys are selling static analysis, so they find themselves using these oversimplified metrics... it's a shame because it looks like there was no lack of real issues.
