They definitely
are anti-consumer and nobody who actually looked into the topic would disagree.
Apple has a monopoly on software distribution on their mobile devices and they force companies to use their IAP api which comes with a heavy fine, which leads to developers (rightfully) increasing the prices. The same goes for Google, the only argument that could be made in the benefit for Google is that it is possible to install Apps from other sources.
Apple is the gatekeeper for anything that gets on their mobile devices (they can't really be considered yours). Apple and the review process are the ones who decide what is a useful tool and what not, what could be considered harmful to their customers etc. This way their consumers missing out at a lot.
Many die hard Apple fans would argue with the perceived sense of security, but recent events perfectly demonstrate that even the most strict gatekeeper, the review process, is insufficient to provide security to unknown users. The best thing companies can do to enhance their users security is to educate them.
The software is not the only position where Apple shows monopolistic and anti-consumer behavior, their hardware repair is another great example but not the topic
