Neither. Either way if you are worried you can always inspect the PKBUILD file before hand.
Also -bin is compiled directly by the creators of browser, so if you trust them and their GitLab - you should be fine, as long as AUR package is maintaned by same maintainer and PKGBUILD diff doesnât look fishy on update 
Not worried, just curious what the difference was.
Thanks for the explanation, was looking to install Brave & LibreWolf via yay.
Donât worry. Pretty good people are creating it. Never had a problem for last 4-5 years. All companies get sold. Thatâs free economy. We canât ask people not to use GE appliances, can we? Or, not to stay at Waldorf Astoria? Or, not to use Reddit? Just because they are owned by someone else, can we?
the people you are talking about have moved to creating vivaldi, thats part of the said concern.
the original creators mostly left opera for vivaldi.
No, I am talking about those who create Opera today, and for last few years. I give credit to the web browser for what it can do, not who owns it, and I am not biased. This bias is the biggest problem of Linux users, they get blinded.
its not exactly bias if one looks into who brought opera, its the same way with things like say, startpage.
it is not only likely to get compromised, opera has been proven a lot of times to already be.
if you dont mind that ti is, thats fine, but when someone proclaims they use a compromised product the sensible linux users just want to bring awareness to it, if you still want to use it after that than that is, again, fine.
So, you wouldnât buy a Motorola, stay at the Waldorf Astoria or post in Reddit, for example? Or, ever buy a Volvo? Just for the bias?
that is why i did not entertain these comparisons, this thread is about browsers.

So, why the agitation, when someone mentions Opera? Isnât it a web browser? We shouldnât be interested in, who owns them but the features these browsers represent. 
Wow I did not know this. I was a big fan of Opera for a long time up to a few years ago. Iâll definitely look at Vivaldi with a different eye from now on. Still not sure if I can rely on it to replace Chromium as a testing platform. I will give it a go though.
You are the only one getting agitated. âSheâ has already politely bowed out of the discussion you should do the same.
I was trying to refer to these features when I mentioned the owner transition above. It is indeed not the features of the browser, but of products of the same company. But still.
Oh, what does (Android) Play Store has to do with desktop browsers?
As you say, nothing. Just an awareness check 
It depends on the situation.
- A browser has a significant impact on the security of your computer.
- Since being acquired Opera has engaged in activities that have proven to be overwhelmingly unscrupulous.
In this case, you should care.
What I am saying is, no one should attack a country, because someone from that country had bought a company. Opera was brought by a Chinese investing company, just like Astoria, Motorola, GE and so on. Thereâs always an underlining hint at that.
I am not using Opera atm, because I found another web browser to play with, MS Edge dev for Linux. Anyway, thatâs all to it. I wonât participate in this any more.
The issue is not only that Opera has been bought by a Chinese company. It is that the specific Chinese company in question has engaged in fairly shady activities. Further, since being acquired by them, Opera has been doing the same. What @anon31549144 linked above is one example of that.
I would advise against using a browser from a company that engages in predatory loan schemes involving 2200% interest loans with unknowing consumers. If you trust a firm that behaves that badly with the security of your computer, that is your choice but I would advise against it.
On the other hand, if you were arguing just for the sake of being difficult, please take that behavior elsewhere.
