I have never personally met Spaceman; I’ve never had any offline interaction with him; and I have never consumed any of his product.
When he first started marketing Spacefoods on these forums, he was unquestionably in spam territory. He was asked to back off, and I believe a few members have even tried to help with his language (his native language isn’t English). He has backed off, he has clearly tried to change his language, and in my opinion he has gotten much, much better.
As someone who was really irritated with the shipping priority changes (instead of giving priority to original backers, size of order was given priority) I was immensely grateful when he and several other entrepreneurs stepped up to fill the gap that Rosa Labs had caused. Since I’m also one of the folks who is not satisfied enough with official Soylent, I’m also immensely grateful that there are viable alternatives.
Spaceman’s post was highlighting a specific problem that some users are encountering, and providing one potential solution, a solution which is not limited to his products and could be completely DIY.
In other words, I see no problem with his comment, but I am starting to find complaints about his comments problematic in and of themselves.
