Um no? And why the Upvotes?

Yes, Jolla didlock the bootloader by default. Why? To prevent an attacker from circumventing the lockcode.

Did they do it to take away freedom from users? No. You can unlock it yourself at any time, of couse you need to unlock your phone for that.

Do they make you pay for it? No they even provide instructions for unlocking!

Hi,

I haven’t done that but I used (and use) Linux smartphones like the N9 and N900 and because I need modern connectivity and a decent camera I got a used Pixel 5 with Graphene. My wife uses an XperiaXA2 with Sailfish so I know the system quite well.

So to answer you:

• Android Apps mostly work reasonably well under Sailfish, expect difficulties with some banking apps and greater difficulties with apps that require Google Play (there are hacks to get microG installed, by now even somewhat officially supported, but she never asked for me to try that). Generally this will make the transition quite easy as you can continue to use old apps if you avoided google dependency on Android. Use f-droid and Aurora store to install them.
• Expect to miss many things from android and falling back to app support to fill your needs. (e.g. good navigation app), but as that works generally well that is no problem. Over time your will replace some of those, but not all, with native apps.
• Expect many features to just work which under android are a hassle. E.g. caldav sync to nextcloud or full and automated wireless backups via rsync and a script.
• Never expect completely smooth sailing. While there is a constant stream of updates the system never reached the polished state of android. Most bugs can be worked around but are annoying. Example: On the XA2 the android app support sometimes looses internet connectivity. Workaround: Stop app support (there is a gui button for that), disable SIM slot 1, enable SIM slot 1, enable app support. Once you get used to it, its quick. Or the browser does not work with some websites and crashes, but you can just use an android browser.
• Battery life with stopped android app support is amazing, even after years of usage the phone only needs to be charged once every few days. Battery life with app support enabled is still quite good with 1-2 days on moderate use.
• Photo quality is lacking compared to current android standards. This may be better on newer phones like the C2.

Overall I can recommend it if you are willing to read the forums to find the workarounds and willing to make some compromises. She uses it as daily driver for many years and has no desire to replace it yet. The community behind sailfish is awesome and the developers often listen to user desires.

To explain this to the uninitiated: (First follow another explanation of the original combo)

In Magic spells are not in effect immediately, instead they go on the stack, before they are resolved. Spells from a stack are resolved in LiFo order, so last in, first out. Instants, like Gut Shot, can be put on the stack at any time by any player (simplified).

So Enemy gets his 21 mana with channel, you let that resolve, he has 1 life. He pumps it all into the fireball, now you act. While fireball is on the stack you cast Gut Shot, paying with 2 life of your 20. It goes on the stack. Your enemy hopefully has no response, without any mana left in his pool, and he looses his last life and the game.

When a player looses the game all his spells are removed from the stack, so you really win and there is no draw.

You stopped his combo with 4 cards worth unreal amounts of money with a single card worth about 50ct.
