The taxes are 'abusive' because they are sometimes very carefully "hidden". Ryan Air is wonderful compared to the nightmare called WizzAir.
The issues with WizzAir:
-Administrative fees of 9 Euro on each flight, for each passenger.
-Trolley bag (10 kg) an extra of around 60 Euros.
-Want have the same fare for 48 hours? Pay an extra 12 Euros.
-After that, checked in bag, is around 40 Euros per flight.
-Check in at the airport costs around 40 Euros.
-Online check in costs 5 Euros, and the say they mail you the tickets two days before.
-They don't mail you the tickets and they don't say anywhere you can only print the tickets on the same day of the flight (atrocious if the flight is at 6 am).
-You can get a refund for a cancelled flight, but the refund link cannot be found on their site. You have a post on Trip Advisor that points to that site.
-If you have paid for a small check in bag (10 kg) but bring that bag to the plane that's an extra 58 Euros (I can live with that).
-The boarding queue may stop for around 15 minutes, because a client needs to pay 58+58 Euros and the boarding attendant is unable to calculate such a complicated mathematical operation, needing the intervention of another boarding attendant (busy). That is a big no NO!
-Of course the web site has "bugs" and you may encounter "issues" that may force you to restart your session, specifically when asking for a refund...
-The "bugs" do not depend on the browser, or the OS (tested on Windows, OSX and Linux).
I don't think there is any evidence of this. Open Source tools fully support Lattice (low end) FPGAs, and support for Gowin FPGAs is not quite as mature.
It seems that many of the initial FPGA patents have expired, and that's why many small FPGA vendors are appearing. Please correct me if I am wrong.
OpenOCD is scriptable/configurable using a small variant of TCL called JimTcl.
