The context of me mentioning is-ought problem is about moral ought, and I did read the text, but I have hard time to see how the problem has been dealt with.
The challenge comes in with establishing a non-arbitrary basis.
There's some discussion on that here:

You might want to scroll down past the first couple posts to where the discussion starts with myself and DrSinger.

There are several components to arbitrarity.
Context and scale are relatively simple to explain:
In the same way we do it in science.
A good analogy is weight vs. mass.
Weight is somewhat arbitrary, since it actually depends on whatever arbitrary combination of forces are acting on an object, based on the planet, and if measured crudely in an atmosphere the bouyant force, etc.
Mass is independent of those things (we'll ignore relativity for a moment), it's essentially context independent. BUT the scale is arbitrary. That is we use kilograms, or pounds, or electron masses, or even some kind of bean. But scales can be converted into each other, and it's not arbitrary to say X weighs more than Y, or X weighs twice as much as Y.
The other is a question of selecting what to measure and call "mass".
Why measure what we do, rather than something else entirely like conductivity, velocity, or how spherical something is?
The answer to that is harder to explain: the teleology of use.
The way we use "mass" in science, measuring anything else instead would basically mess everything up. We'd have to redefine every single term, and then come up with a new term for what we now call mass because such a concept would still be needed.

The quality of having interests is not an arbitrary one. It's not specified at random.
It's not at all like selecting the quality of how many toes something has or how long its digestive tract is.
What we are fundamentally talking about with morality is value systems, and these can only be measured in terms of value systems.
Another analogy:
What is the mass of that bus in kilograms? A very answerable question (even if you might not know it).
What is the mass of that bus in pinto beans? If we take the average mass of a bean, still a somewhat answerable question within a margin of error.
What is the mass of that bus in hours? Can you answer that?
Mass can only be measured in terms of things have have mass (or at least energy). Hours do not have mass. You could arbitrarily make up a mass for an hour, but you'd be no more right or wrong than anybody else making up a completely different mass.
When we deal in objective metrics, we're looking at what can be established objectively, whether it's in terms of kilograms or beans.
So, for a value system, we must measure it in terms NOT of toes or the dimensions of intestines or "abstract thought", but in terms of values: preferences, interests, etc. Things that are fundamentally related to values and have an innate exchange rate.
Sentience itself isn't a value, but it indicates that the organism
has values to consider (unless it's catatonic or something).
Capacity for abstract thought isn't a value, but it may indicate that the organism also has
additional abstract values to consider (in addition to whatever "non abstract" values the organism may have from being merely sentient).
In order to be non-arbitrary about it, we can't arbitrarily discount values that don't derive from whatever we arbitrarily consider "abstract thought". Just like we can't measure mass and claim that things that are blue don't count to the total.
Abstract thought probably means a being has a lot more moral value (because it has a multitude of additional values/interests/preferences deriving from that abstract thought), but what we're looking at on a fundamental level to establish objective morality is the presence of interests.
