3e was a direct successor to 2e, but mechanically it was a new thing, and "spiritually" it was probably more a successor to 1e. 5e seems like mechanically it's a successor to 3e, with some of the ideas of 4e rebranded, but I guess I can see that maybe it's a spiritual successor to 2e, at least maybe when it launched. But that's a harder thing to demonstrate, and it much more about "feel" and subjectiveness. And I think from a marketing standpoint, they've certainly migrated more into a later 3e style release schedule, where they're hoping to sell more player-facing books, so the game itself has become more player-facing and player-focused rather than DM-facing and DM-focused.
The OGL debacle certainly feels like TSR's draconian C&D online approach during late 2e, and WotC's 4e approach, which felt much less open and customer friendly, but that's not an aspect of either of those editions that they should want to emulate.
