But nearly every product you use has a marketing budget and the only reason they are around is because they spent that budget.
To me, marketing is a sign that you are serious about your product and you are willing to spend a lot of money to promote it. It’s not a sure sign of a good product still but there’s no such thing anyway.
In a world without marketing, there would be 1000 identical versions of the same product and I would have no idea where to begin. see: all the unmarketed direct-from-China clones of more or less the same product on Amazon with weird brand names
