lol, ok bro

Friend, this is NOT how you talk within public for a product which mind you, might handle sensitive information.

Some people (myself included) will not like subscription-based, web app.

You worked 7 months on this project full time on your savings as you mention and you might've squandered any reputational gains from that with just three words and a comma.

Might as well go down in the history of hackernews but a bit negatively. I hope that you take a deeper look at how you respond online.

I have a suggestion but if you feel like you are not sure how to respond to a comment, then don't at the moment rather than typing this for example.

perhaps treat it as a learning exercise on how to answer such questions because if you ever market to anyone, customer or business. It is natural that they will ask such questions and so in a way, it might be beneficial.

Just my 2 cents.

Anecdotally, it takes a lot of patience to answer criticism in a good manner and definitely takes a lot of time to craft a good answer if you do go through that route but in the long term/even in the short term, those are some of the best messages that I have written personally which genuinely make me appreciate myself.

I wish that you can take a deeper reflection into such question as you are most likely going to be asked it quite often and having an good answer early on might be beneficial for your product.

have a nice day.
