Not true, even for murder stats. It’s perfectly reasonable to challenge the accuracy of the numbers. The FBI and NYC use the same definitions for murder and starting in 2023 and 2024 their numbers haven’t matched. The FBI is reporting -13% fewer murders in 2023 than the NYPD recorded and -47% fewer murders so far in 2024.

If you look at absolute numbers, the NYPD is recording year over year increases in major violent felonies whereas the FBI is saying there are year over year decreases.

What makes it worth it? Isn't the experience the same as just running an ad-blocker?

Perhaps, but the difference between now and then was all those years had near-zero interest rates. It's a lot easier for tech (and growth companies in general) to stage a comeback in that macro environment. Especially when it comes to issuing all the RSUs to fund those compensation packages.

They've only killed off one version of self-hosted Jira. Their datacenter edition is still alive.

Lighter oils get used for gasoline, diesel, and aviation fuels. Heavy oils get used for plastics, petrochemicals, and road surfacing.

I wish there was an easy answer to your refinery question. They're all different, but there are three basic types of refineries:

The simplest is a topping plant, which is basically just a distillation unit. The output you get is basically whatever the natural yield of the oil is. These refineries can typically only process light crudes.

The next level refinery is a cracking refinery. These take the gas oil output from the distillation and breaks it down further using high temperature, pressure, and catalysts. This allows for the breakdown of slightly heavier crudes.

The final level is a coking refinery. This takes all the residual fuel and "cracks" it into a lighter product. This increases the yield of higher value gasoline, which allows a refinery to take in cheaper heavier crudes.

Building a new refinery is a 5+ year process that costs about $7-10 billion. I'm not sure what upgrading an existing one costs, but it's somewhere in that ballpark. Keep in mind that a large influence on the type of refinery is their geographic location. They're built to accept the type of oil that flows in the pipelines.

It's not just a matter of building more refineries to process it. The different API Gravities of the oil are used to output different products. Gasoline, jet fuel, etc.

So yes, you could modify refineries (at significant expense) to process different grades of crude, but in order to target different outputs we still need to import the different grades of oil because the refineries end up mixing/matching to get the levels they need. The US produces a lot of light oil, but less of the medium/heavy grades you'll find in Canada or the Middle East.
