It’s absolutely not true that it’s a “people problem” not a “tech problem”.
Tech companies have deployed many billions of dollars, and the smartest minds in the world to ensure that their little fiefdoms are the ones that become the internet.
First, they deploy psychology and tap into basic human behavior knowledge, to ensure people are addicted to their platform and spend most of their time there instead of anywhere else.
Further, companies like Apple originally made it difficult for an open source, or a hobbyist to create an app that can be distributed on iPhones, first by instituting their $100 dev account requirement, and then building an insanely Kafkaesque approval process.
Then there’s the bait and switches. Google went ahead and bought Blogger/Blogspot when it got popular and then stopped investing in it beyond making it easier to insert Adsense. Then Google destroyed the non-Twitter sharing ecosystem by bringing the majority of the RSS ecosystem to Google Reader, and killing it basically overnight.
Apple used to provide simple personal website publishing with their iWeb products, which they pulled.
Then there were the non investment and destruction of Flash, which had become a huge source of internet creativity with no equivalent alternative. Apple famously killed Flash, and probably for good reasons considering Adobe was focused simply on extracting money from it, but Apple didn’t bother creating any authoring tools that made it possible for random middle school kids to create cool stuff with.
Facebook originally presented its pages as something that would be openly accessible to the internet. But once people created a bunch of them started requiring logins.
We rightfully criticize MS for their embrace, extend and extinguish strategy that they’ve deployed against so many of their competitors. The reality, however, is that even “better” companies like Apple, Google, have done the same thing, except they’ve done it to the Open web, and because the open web doesn’t have billions of marketing and lobbying dollars to complain, we didn’t even realize that was happening.
