Three neighbours in line-of-sight is not rural. Maybe semi-rural, but not rural.

It would be considered rural in Norway at least
And line-of-sight could be several miles away, seen from 3m above the roof-top, and still be very workable.
I doubt other operators would purposely sacrifice two satellites just for testing reentry, particularly when 3 are already doomed for reentry.
Sure, but the other 3 are uncontrolled reentry eventually. These 2 were controlled.
Yep, and the other 3 will re-enter in some number of years, not right now when the data is most valuable to SpaceX.
Ok, so what gives: Bloomberg - Are you a robot?
Does Bezos wake up each day wondering what part of SpaceX to copy? Or has he realized that there isn’t enough launch business, so he needs to vertically integrate an application as SpaceX is doing?
At any rate, we are going to awash with satellite broadband.
The market numbers in that article are interesting because they are so low. It says only 21 million Americans are without broadband, so I suspect that “broadband” is defined something like 5 Mbps or better. These days, a 30 Mbps is too slow.

Till 2015, it was 4Mbps up/ 1 Mbps down. Then it became 25/3. Powell was trying to reduce the standard to include cell coverage as sufficient (versus requiring both)

Also (in general) : these constellations are world wide coverage vs geosynchronous with specific spot coverage.
I'm on DSL at <8/4, no cable available.
If that's what you got from the [months old] news that Amazon is, like a bunch of other entities, looking to put up an internet constellation, I'd encourage you to review the history of satellite internet and then the history of Amazon.
More so than pretty much any other entity in the game, it has been a foregone conclusion that Amazon would at some point put up a constellation to support their continuing efforts to take over the world. That they chose to wait until this year to officially announce their plans is indication of nothing--positive or negative--other than their business strategy.
AWS would likely benefit from its own back haul network. Fault tolerance, if not bandwidth capacity.
Four more launches, maybe.

ArsTechnica analysis of the ESA incident SpaceX satellite was on “collision course” until ESA satellite was re-routed
So... to do an altitude adjustment for collision avoidance efficiently, they need the burn to occur 1/2 an orbit ahead of time (or 1.5 or 2.5), but no one ever explains that is due to orbital mechanics. Without a KSP background, the whole 1/2 an orbit before collision sounds last minuteish/ alarmish.
Or am I just pessimistic about news coverage?
Maybe Ars assume that readers of its space-related articles know some basic orbital mechanics and realize that spacecraft and satellites cannot actually zoom around space like they do in Star Wars.
Whats curious is that, near as I can tell the lowest starlink is at 350km (including tintins) and Aeolus is at 320km. I suppose there could be a Starlink with some eccentricity, but I'm not about to dive into an endless google search.
This is the lowest starlink.

Matt Desch @IridiumBossHmmm. We move our satellites on average once a week and don't put out a press release to say who we maneuvered around...
So a friendly SpaceX customer is turning the tables on ESA, basically stating this is no big deal. The story got plenty of media attention in the last 24 hours, even heard a segment on NPR Tuesday. Seems like a calculated ESA hit job on SpaceX, but of course I'm biased as all hell. Credit SpaceX for taking the high road by issuing their statement.
Further down in Matt Desch's Twitter feed he was asked if Iridium charged the owners of the satellites they maneuver around. His response, "I wish. We’d make a heck of a lot if we could."
