Article highlight some great points. But I think Feature flags bring value where we dont need to rollback code if its failing. Also failure so not so straight forward in most of cases where we enable a feature and it fails. Sometimes it degrades performance over time, sometime you want to enable it slow to understand its semantic under production traffic, sometimes we want to enable something around some launch date etc.

For sure, it brings extra complexity in code because of left over flags which are not cleaned up. Not only complexity which is added while writing flag but later new code also added for all these condition to unsure compatibility. Cleanup should be managed like tech debt but its not unfortunately.
