Musk just yesterday asserted that it was time to deorbit the ISS.[1] Decommissioning telescopes would not be out of the question.

Not only does Musk have a lot of power to get favors granted to him now, but I'm sure he also realizes that there could be significant backlash against him and his companies during a future administration, if his and Trump's actions turn out to be as broadly, bipartisan-ly unpopular as I'm hoping. So not only will he want to extract as much as he can from the government now, he'll want to consolidate and increase his lead over his competitors so a future administration may have no choice but to continue using SpaceX for the bulk of its needs.
And on the topic of dead end technology, let's face the fact that the ISS is just Mir 2 with US participation. The DOS-8 module it's built around is the module Mir 2 was to be built around, Mir (1) being DOS-7, and the previous DOSes were the Salyut stations. Direct hardware lineage. The only reason these things exist in the first place is because the Soviet Union though space stations would be good for earth observation, a role they are wholly obsolete in now, but once the Soviet Union started building something they liked to keep building it long after it made sense (see also, the Vostok capsule, which they are still using as a satellite bus to this day.). And the only reason the US is involved in this is literally welfare to the Russian aerospace industry to prevent their engineers from having to seek employment in Iran/etc. In this role too, it is obviously obsolete.
Now a word about Mars, because I can already sense somebody about to accuse me of being a senseless musk fanboy. Mars colonization makes no sense and musk is lying about pursuing it. For a Mars colony to actually become a "backup for humanity" of whatever drivel he claims, it would need to bootstrap itself into self sufficiency, which at the very least would require a viable economy for trading with Earth. No such economic plan for a Mars colony exists. Furthermore, SpaceX isn't even investing in the creation of the requisite colony hardware, the habitats and Martian industrial infrastructure which would be required to make it work. What they're actually doing is far more mundane; building rockets for launching satellite into Earth orbit. The Mars talk is just a recruitment tactic to pull in young idealistic engineers and get them to work long hours for cheap.
His move away from the previously-stated mission for Tesla to decarbonize the world's energy systems makes a lot more sense now
