How many administrators have experience / knowledge of Mattermost? How are you going to recruit staff for that?
And in theory you are right, in practice it turns out too often that this is not the case. In addition, there is also sometimes documentation missing, something os. ITers seem to hate … And if it is there, the question is, is it clear, correct and / or up to date?
These kinds of solutions are more likely to be encountered in ‘shadow IT’ and then it can be very nice that the entire crowd that ‘managed’ this has left the organization (voluntarily or not) and then it is even finding out what it is all about. It will not be the first time that you are pulling network cables out on switches, while yelling to a colleague “Is that site still available!”
How much extra time does a user spend mastering Mattermost? How much time does management, servers, redundancy, space in server space, backup, update, etc. take?
