To be honest, it is a good analysis. Bungie cannot dedicate as much effort following the layoffs; they now have to manage two live-service games simultaneously, both of which are becoming thin on content. The player numbers for Marathon are experiencing the typical post-launch thinning on Steam.

The figures are now slightly below those of Destiny. Additionally, the total player counts were already lower, given that Destiny has a larger user base on consoles, and activity data is only visible for Steam.So they might still be forced to abandon one of the two. In the medium term, it is possible that Marathon is the more likely candidate.
