I think that what they wanted to avoid (but put 0 effort into explaining it) that's actually understandable, is using the CT to be used as a home battery a lot, and still try to have the 8 years of warranty, because you're driving 0 miles, but degrade the battery as if you drove 1,000,000 miles in those 8 years, then ask for a replacement after 7.5 years.
1,000,000 miles sounds too much ? Let's do some math if it's possible. Let's assume that the battery has 100 kWh energy capacity. It's good to not use 0% to 100%, so let's say the usable capacity is 60 kWh.
11,5 kW, means that if full, it will discharge in, say, 6 hours, rounding up a bit. If recharging from 20% back to 60% again, it would mean it needs 10 hours just for the discharge part to cover 100% of the battery capacity. That means it's totally doable to have a full charge-discharge cycle in a day. Also, that would be like driving about 300 miles
What does 7 years mean in terms of days ? 7 * 365.25 = 2556.75 days. Let's round that to 2500
So, 2500 days means potentially 2500 battery cycles. I read somewhere that they officially said that their batteries can be used for 1500 cycles. So that's already over the limit.
Also, 300 miles * 2500 = 750,000 miles.
Ok, so I was off, but it's still 5 times over what they would've covered, if you used it to drive, not to power a home or whatever. And it is over its expected life time.
To put it in another way, 150,000 miles would mean it only needs 150,000/300 = 500 cycles, about 1/3 of the battery lifespan.
Still doesn't excuse what they wrote. Or Elon being a gigantic jerk that needs to be jailed, along with the many people that enabled him to go this far.

Just realized that they're incompetent not only from failing to word up to cover the potential case I explained above, without also including totally BS opportunities to not cover the warranty, but they're also so incompetent that they failed (I think, I didn't read that whole thing, only what Louis showed us) to also exclude another edge case that's not their manufacturing fault (though you can say it's their marketing fault for making the claims, so ... I'm not sad if they get punished).
So, here's the thing. The CT can tow about 5000 kg (11,000 of caveman-age freedom units). And from several reviews I've seen, when doing that, the range is only about 100 miles (yeah, I should use km, not miles, but I'm lazy to do the computation when all the given details are already in miles).
That means that you can have one full battery cycle for only 100 miles.
How many cycles would then 150,000 miles mean ? Exactly 1500, which is the expected life span of the battery, so it's basically guaranteed that it won't still be over 70% of its initial capacity. So they' have to cover its replacement.
Though to be frank, they also say that they won't give you / restore you to a brand new battery, just one that is in spec (aka working and above 70% capacity) so they probably aren't losing much on a repair like this. Still, you could theoretically do this multiple times. In reality they'll surely deny service.
