A healthy competition is always good for the customer but I have my doubts on the healthy part.

A flood of fly by night products with low effort mess is going to lower the trust in genuine indie development products and could drive users towards established names in the industry.

In some way it's like the new PR flood on github. On the surface more PRs looks like a positive thing but it had unintended consequences.

Like the famous Market for Lemons, where a similar information asymmetry produces market failure that ends up making things worse for both buyers and sellers.

New signals of trustworthiness will emerge (are already emerging.)

More shots at the big names is not going to entrench them, even if most of those shots don't go anywhere.

The big names also need to stay competitive against internally developed solutions inside what would have been their bread-and-butter enterprise customers, so they have to compete on features and quality like indies.

Now we have 100 fly by night vendors! Awesome!

Reputation will matter more than ever before

How do you build reputation when you have 100 competitors who will do shady things to get customers before pulling the rug out from under them. Your pockets aren't deep enough to survive until there are pieces to pick up.
