You’re contradicting yourself. If the logo doesn’t matter, then using a generic vector isn’t a problem. In fact, it is better than paying for any “logo maker” because it’s free!

I have no qualms with companies starting out and using something generic to make due, as long as they understand the difference. But the dozens of logo maker websites including yours all sell themselves as if they’re the same as a custom logo, and they’re not.

Also, the name and domain do matter. I’ve seen projects fail because they inadvertently named themselves after a negative word in another language.
