I am genuinely asking, what on earth do y'all think "monopoly" and "anti-trust" mean?

It's baffling to me because some users on HN grandstand so much about how making your own product or platform means that you are morally obligated to support any and every third party under the sun. But then the actual tech industry seems to be the direct opposite - if anything companies make lots of fanfare out of achieving basic interop.
