IANAL, but my understanding is that as long as you only provide the knowledge but not the actual software you're fine. e.g.: conducting paid training sessions, even ones where the attendants are required to download the software from the official site and install it on their machines for practical exercises, should be okay. If someone wants to pay you to install licensed software on their production machines and configure it... Eh, probably not. Also to reiterate that Redis itself is still BSD, so if you're not using add-on modules licensed with this clause you're unaffected. Full disclosure: Am a Redis Labs employee, although not here in any official capacity.
