I agree. There is a clear way that Dropbox hurts Apple's business interests. Many Apple devices don't have a lot of space. The current generation base Mac Mini and MacBook Pro both only have 256 GB of storage. The iPhone 14 Pro starts at 128 GB. So, many people in the Apple ecosystem rely on things like iCloud Drive not only for backup storage (like storing only important files) but also for the bulk of their storage (as the device space is so limited). The 2TB iCloud Drive costs €10 a month or €120 a year. That is a lot of money over a device's lifetime - about €850 for an average MBP (which on average has a 7 year lifespan). And Apple users really feel the pressure to use these more expensive iCloud Drive plans. Unless there is a competing service targeting the same price point (and even a slightly lower one with an annual subscription). So it makes clear business sense to kill the competition. Every other explanation is just a little bit more contrived than the straightforward business case.
