I have never had marine snow foul my water. It may not be the best product out there, but it isn't as bad as you make it sound.
If you dose in small quantities it won't destroy your tank. The issue is, do you notice it making any difference? Most people don't when they really start to pay attention to it and in that aspect, it makes the product just another pollutant in the tank. There are far better, more effective, less pollutant products on the market. With the bottled products such as Marine Snow, there is no way to know what the conditions of the product were during shipping, ie, cold weather freezing the snow, then thawing it will make the product pure garbage in a bottle, same with high heat. Since these types of products are usually shipped general freight, there is no temperature control to make sure these sorts of issues do not arise and general freight compartments are usually very, VERY cold. The other issue that comes into play is how old it is. You have no way of knowing when it was made and how long it's been sitting on the shelf at the LFS before you bring it home and dump it in your tank.
Seriously, do the 5gal test as I listed above. 5 gal of water and a cap full of Marine Snow, test levels. Not so nice
