No, they didn't. They gave at least 6. On on the off chance that you are arguing in good faith, here they are:
Changes in API and technical aspects: OP mentions having to shut down their bots due to changes in Reddit's API, suggesting that the platform is becoming less friendly for developers, especially those who contribute to the community by creating bots or other tools. This could discourage tech-savvy users or developers from using or contributing to Reddit.
Financial costs: OP notes having spent a significant amount of money maintaining their bots and server infrastructure. While this may be specific to people who run bots or subreddits, it indicates that participating in Reddit in a significant way can entail considerable personal financial investment.
Concerns about leadership: OP cites the behavior of Reddit's CEO as a reason they would not repeat their investment in the platform. This suggests that ethical or moral concerns about the platform's leadership can lead users to disengage. And really, that's a very valid concern; given how detested Spez is.
Loss of community members: OP predicts a "brain drain" of bot developers and tool creators. This loss of key contributors could degrade the quality of content and interaction on Reddit, making the platform less appealing to both current and potential users.
Change in the platform's character or values: OP expresses a sense of loss about what Reddit used to be, indicating a perceived shift in the platform's character or values. Users who identified with or were attracted to Reddit's earlier ethos may feel alienated by such changes.
Loss of tools: The mention of Apollo, a popular third-party Reddit client, suggests that the discontinuation or loss of favored tools can also lead users to abandon the platform. It implies that changes affecting such tools, whether due to Reddit's policies or other factors, can negatively affect the user experience.
