I think if your view of the crypto space isn't so myopic as short term price (1 week time frames) ranges, whether a coin will pump immediately you'd find that the discussion really has to do with the crypto space as a whole. If you have a general understanding of LISK everything they talked about impacts LISK.
The governance, philosophical and intellectual ideas Hoskinson has towards the entire crypto space will directly influence LISK as a senior advisor.
Personally, he very briefly discussed the 'tribes' and factions that have come out of ETC/ETH debate. I immediately thought that in relation to LISK the logo doesn't clearly define an attraction to a certain group of people. I think an overhaul will come, any marketing professional will quickly change the entire marketing look and feel to attract more people adopting a more populous approach.
Hoskinson definitely has a "code is law" bent, which I personally agree with. I think human behaviour even if you do the right thing 99 times out of hundred depending on the mental, physical and overall health of the people involved they can slip up and make bad decisions. The 1 bad choice out of 100 can have massive impacts. I personally think Vitalik was under a lot of pressure to do the right thing with probably a million voices influencing his decisions.
If Vitalik had left it alone, I am 99% sure a better (moral) hacker would have solved the problem without forking the chain.
If you want Hoskinson has talked at length about LISK and his reasons for joining. Here:

But as you'll see in the video it's about the entire space, LISK will be moulded in relation to the entire space and what works best with the team they put together. The best companies solve problems identifying the need for side chains and other code bases definitely has it's place.
Reading the white paper and listening to different interviews, there are some very smart, talented and well intentioned people on board.
Thanks for the markers to watch at. You are right, that ETC will likely have an impact on Lisk given Charles's involvement, in that IOHK would be a strong candidate to port EVM over to Lisk as a blockchain app connected to Lisk. Lisk may even have ETC integration, though it would make business sense to have ETH integration as well. ETC does have some strong support in the Lisk community. My own preference is for ETH, but the market and ability for ETC to gain developer support and organize will be the deciding factors.
