Perhaps you were never deeply involved in WT study etc. and your understanding of ‘watchtowerspeak’ is not too strong. I’ll help you out there,
The “parable of the talents” in WT understanding was always applied to “the anointed” only. As ‘doubtingbro’ pointed out, “ I always thought they used that verse to reinforce the need to obey the GB.“ This is a correct observation.
The WT article at par. 6 is teaching the masses of common JWs that they gain “.... strong encouragement to continue serving Jehovah faithfully!” from this illustration. That “encouragement” can only be possible if they are included in;
“the faithful slaves ..” who “... were faithful over a few things” and whom Christ “will appoint... over many things”.
The focal point of the parable of the talents, in WT world, was the “anointed” (read GB) and the dubs get salvation by doing good to the GB by selling their GB winsome words to the world.
The NOW Watchtower teaching is morphing. The common dubs, not just the “anointed”, are included in the “faithful slaves” in the parable -who will be rewarded.
In line with that change was the talk at the DC that said rank & file dubs are counted worthy by Christ by doing good, not just to the GB (preaching WT crap) , but to any in the congregation.
Perhaps spend some time getting a better understanding of historical WT teaching on this and it will be easier to understand what’s changing.
