I think you might be neglecting somethings that constitutes a moat. IMO Zoom has an enormous moat based on network effect. To a large extent this is the same moat that Alteryx has. It’s the same moat that Facebook and Netflix has. I’m sure if you were to think on it for a while you could come with several many more companies that rely on network effect as a major contributor to their moat.
The security issues associated with Zoom are real and that’s a rather large oops. But I don’t think it will badly impair the company long term. As to how many enterprise users abandon Zoom in lieu of Blue Jeans or Webex or something else I think it will be a blip rather than a route. In addition, Eric Juan, Zoom CEO was quick to accept responsibility for the failings and very responsive with respect to taking urgent steps to rectify the situation. He has gone beyond just fixing the problem. He asserted that security will be a primary consideration for the company going forward. There’s a big difference between saying, “we messed up, we’ll fix it”, versus “we messed up, we’ll fix it and we’ll alter our process such that security will be at the forefront of everything we do from now on”.
So you’re basically asserting that the disruptor is subject to disruption. While this is true in theory, how many examples of this happening can you name? I can’t think of any, but I haven’t made a point of studying this topic. Zoom is still the leader with respect to innovation in this space. It will be years before the face the dilemma that companies like Cisco and Intel and countless others faced. When they get to the point where innovation threatens to cannibalize their own business there will be something to be concerned about. IMO, Zoom is the undisputed leader in the market and will very likely remain so for several years to come.
