The fact that giant companies eventually collapse under the weight of their own greed and complacency doesn’t mean they don’t engage in anticompetitive behavior while they’re at the top.
My point is huge companies can engage can have negative effects on competition even if they eventually fall.
How many businesses has Amazon whipped out in the retail space by leaning on the profits from the cloud division?
Just the other day we saw documents from the DOJ’s lawsuit against Google for anticompetitive behavior. In the those documents we saw internal communication about a desire for Google to use their dominance in the browser space to create the web into a walled garden [0].
Those largest companies from 20 years ago didn't fail, they are all doing very well (well, GE excepted), they just did not grow nearly as fast as new tech did.
