Kolibri's decision to not adopt checker could have been due to a variety of factors. It could be because they didn't believe checker had enough potential to be successful, or that the cost of integrating it into their platform would be too high. It could also be because they didn't think the technology was mature enough, or that the user experience was not up to their standards. Whatever the reason, it is clear that Kolibri chose not to adopt checker in 2020. This is unfortunate, as checker has the potential to be a powerful tool for businesses. It can be used to automate tasks, streamline processes, and improve customer service. Unfortunately, it appears that Kolibri was not convinced of its potential and so they chose not to adopt it.
