The biggest difference is that MPL allows static linking while LGPL does not. While in the past this wasn't a big deal, it is important for iOS development since you cannot dynamically link to libraries in iOS apps.

His space station company:
There is no way that any merchant account provider would allow you to sign up and start charging customers in 5 minutes like Stripe lets you.
Moving to other countries will take time as each country has their own banking/financial/etc issues that need to be dealt with.
It took years for PayPal's Web Payments Pro to go from US only to US, UK. And then a few more years to go to US, UK and Canada.
Amazon FPS has been around for ages and is still US only.
So it may be a while.
What will be more interesting is if they can match both Amazon and PayPal's microtransaction rate of 5% + $0.05 for products under $10 (Amazon) to $12 (PayPal).
JSON-based HTTP API
PHP, Ruby, Python and JavaScript Support
Setup in 5 minutes.
No branding requirements or redirects.
5% + $0.30 per transaction.
US Based Sellers Only.
Recurring Billing Support.
Data Portability if you ever want to leave.
You pay all initial fees (5% + $0.30) if you issue a refund.
You will only receive money at the end of the next month.
The fees for Stripe are 5% + $0.30.
However when you take a deeper look you see that things are not so simple. Compared to PayPal's free product, you are not forced to leave your website and go to a 3rd party site to complete the transaction. Compared to PayPal's Web Payments Pro product, you don't have the $30 monthly fee.
Also this doesn't even taken into consideration the complexity and cost of implementing PayPal's Payments Pro api vs Stripe's simpler JSON api.
