Nearest competitor to Helium's LoRaWAN deployment that I'm aware of is The Things Network[1] which has no incentive model and instead people often host an access point for their personal use and sometimes for the use of those nearby.
Helium is expanding to CBRS[2] 5G service which will offer traditional higher bandwidth services, but this deployment is very early and the first units are shipping next month from FreedomFi[3].
Coolest thing about the Helium LoRaWAN offering is that you can buy a $20 ESP32 microcontroller with Lora radio on Amazon, write some software, buy Helium data credits and use it anywhere helium has coverage. No contracts, no special hardware. And if it sucks you could switch your application to use another LoRaWAN offering (The Things Network). That said, I think the coverage of Helium vastly outpaces anything else because of the crypto incentives fueling the madness and growth. [4]

Or just go with the free TTN. But I do agree that it's good to have icentives and I'm quite glad somebody is rolling out a large scale LoRaWAN.
That landing page is sparse but Helium and other wireless networks are using blockchains as a rollout strategy.
Basically people invest in radio hardware because they think they can earn more in the blockchain token, don't worry as the radios are low power and most networks especially Helium's doesn't allow people to hoard radios, you earn less if there are other radios in the coverage zone. Other radios are the nodes which report your adherence to the network rules, the blockchain automatically pays out. Thats the supply side. The demand is people and organizations buying the token to buy send data over this network. With Helium I believe thats a one way conversion: Helium tokens -> data. But the receiving radio gets paid in new Helium from the blockchain's issuance, if it received any data then thats a bonus added to its payout allowance (but its not 1:1 to the amount of Helium tokens burned). So its kind of fun to think that the availability of this wireless network will have some service buying this digital commodity as an overhead cost and extending service to people that don't know Helium is one of the network routes behind the scenes. There are some IOT device that use the Helium network, I think some of the rideshare scooters use it already for over a year.
The way this works is Helium hardware owner/operators deploy CBRS radios in whatever real estate assets they have at their disposal, then Helium or the Helium OEM partners with MNO/MVNO to offload data at a very cheap rate, and suddenly the carrier can grow network coverage at zero capex and low opex and the Helium node owner has a new source of revenue which was never before possible.
They also open the door to become a semi-private network infrastructure too, which would be in competition with this new Amazon product.
The fuck
But for a moving device (ex: truck) transmitting locally stored data without latency concerns (ex: IOT temperature readings for a frozen cargo) I think it would be much more efficient, with far more coverage: you could have a $20 LORAWAN ESP32 built in individual boxes.
Think of this like Apple airtags, using a mesh network to intermittently transfer data on a best effort basis, but hooked to custom sensors so you fully control the payload
Hard pass
In this case the only reason for the blockchain is really because global payments are hard.
Helium is a useless concept (in practice) that is now getting on the 5G trains for marketing purposes. Their IOT is super-low data rate for anything useful. It is good for people to thinker and speculate but no use for real life applications that demand actual throughput.
