The general idea behind capitalism is that the market provides alternatives. Why would there only be evil giant corporations whose applications are so bad that they would be trumped by those great ancient, obsolete applications? There is also room for small vendors to provide innovative new alternative, and for the open source community to try their hand.
The reality is that on the Apple platforms these ancient, obsolete applications are not available and instead there are new, modern, better applications because there is a market for them. While on the Windows platform it’s a big, inconsistent insecure mess because everyone is clinging to obsolete, unsupported software that is barely good enough.
By the way, keep pressing that button you think is the disagree button!
