Why are so many people pretending this is being done for the good of the users? I got started in my business because I loved what I was doing (for my users). I stayed because it makes me a boatload full of money. If I see my competitor slipping, I want to take advantage of them. Sure I do have empathy for the users but at the end of the day it is pretty clear.
Believe me, if your competitor saw you doing this stuff they would definitely report you. Kill or be killed. You think Marc Cuban or Donald Trump is worried about their users when they have an opportunity to take advantage of a competitor?
If your competitor saw you doing 'this stuff' they might report you, they might not. It's not a certainty and having seen enough situations like this over the years it strikes me as immature to think that by damaging your competitor you are immediately strengthening your own position. Rather the opposite, you are damaging the entire field in which you operate, which includes your own company.
Second, it's not kill or be killed, if that was all there was to it then why not hire some Russian goon squad to bring down your competitors web-site? After all, they could do the same to you... Most likely the idea that all of the competitors business would be taken over and that they'd go spectacularly bust is a pipe dream at best.
And let's let Marc Cuban speak for himself (as far as I know he's not going to stoop so low as to intentionally damage a competitor for his own advantage), for Donald Trump I'll hold up the inconclusive data flag.
If you run your business the way you do then it will definitely reflect back on you in most cases, you'll find that one day the tables are going to be turned and then you'll be all out of sympathy.
Sure, business is ruthless. But it does not automatically mean that you can back-stab your competitors for your own glorification. And if it does then I'd rather not be part of your circle, toxic attitudes create toxic environments.
If you think that the only way you can grow your company is at someone else's expense then maybe it's time you spent a few $ on marketing instead? Very rare to find an ocean empty of fish.
