I'm totally new to this space but my thoughts are:

Bitcoin gold isn't a beautifully polished presentation with a glossy website.  People expect to see this as the de facto nowadays.   Without the glossy marketing people think that it must be a scam.   Often the best restaurants are mom and pop joints - maybe don't have the best location like McDonalds but they do have the best food.  Don't judge a book by it's cover, all that shines is not gold etc..etc

However, one thing for sure is that all most successful  scams - banking system, Clinton, pyramid selling always have the best looking brochures!   Maybe these guys are just trying to do something good and really are not into wasting their efforts on advertising.
