This seems to be split pretty clearly down a "promotion criteria" line. At small companies, where basically everything is arbitrary, sample sizes are small and there's not enough data to be data driven, titles are perceived as mostly meaningless. At large companies that do a good job of standardizing how promotion works and what is required to get it, titles are not perceived to be meaningless.
