That's a bold statement. Font lock can involve arbitrarily complicated regular expressions (maybe even arbitrary code?), and depending on the major mode it can be slow. Typical examples are large latex or org buffers. The advice to report occurrences as a bug is sound, but if it's not a core mode, the bug report should probably be addressed to the relevant developers.
