Doesn't look similar. It looks identical aside from the colors. Looks like someone used the Roatz one for template and pasted Stargaze into it, changed the colors and called it a day.
Honestly don't think it's really a problem though. You paid someone to make your logo and thread design, they delivered the same shape that Roatz has for the logo and a previously used shape of a thread design. If anything, you're the victim here it seems.
Not sure, but I think Baroko just pointed it out because it was a bit funny. Which it is.
