And for historical reasons. The forward path started at TV channel 2. The

Originally this didn't matter much because the only thing it was used for was
set top box communications and occasionally sending video to the head end for
community channel remote feeds.
To change the split would require replacement of all the active and passive RF
equipment in the network.
Only now with he widespread conversion to digital cable are they able to free
up enough spectrum to even consider moving the split at some point in the
future.
Something else to keep in mind, is that the cable companies wanted to
use the
upstream for voice using DOCSIS QoS to create a big advantage over anybody
else who might want to just do voice over the top.
There was lots of talk about business advantage, evil home servers, etc, etc
and no care at all about legitimate uses for customer upstream. If they
wanted
to shape DOCSIS to have better upstream, all they had to say is "JUMP"
to cablelabs
and the vendors and it would have happened.

As I said earlier, there are only so many channels available. Channels added to
upload are taken away from download. People use upload so infrequently it would
be gross negligence on the provider's behalf.

You do of course realize that the asymmetry in CATV forward path/return path
existed LONG before residential Internet access over cable networks exited?

Can we stop the disingenuity?
Asymmetric service was introduced to discourage home users from
deploying "commercial" services. As were bandwidth caps.
One can argue all sorts of other "benefits" of this but when this
started that was the problem on the table: How do we forcibly
distinguish commercial (i.e., more expensive) from non-commercial
usage?
Answer: Give them a lot less upload than download bandwidth.
Originally these asymmetric, typically DSL, links were hundreds of
kbits upstream, not a lot more than a dial-up line.
That and NAT thereby making it difficult -- not impossible, the savvy
were in the noise -- to map domain names to permanent IP addresses.
That's all this was about.
It's not about "that's all they need", "that's all they want", etc.
Now that bandwidth is growing rapidly and asymmetric is often
10/50mbps or 20/100 it almost seems nonsensical in that regard, entire
medium-sized ISPs ran on less than 10mbps symmetric not long ago. But
it still imposes an upper bound of sorts, along with addressing
limitations and bandwidth caps.
That's all this is about.
The telcos for many decades distinguished "business" voice service
from "residential" service, even for just one phone line, though they
mostly just winged it and if they declared you were defrauding them by
using a residential line for a business they might shut you off and/or
back bill you. Residential was quite a bit cheaper, most importantly
local "unlimited" (unmetered) talk was only available on residential
lines. Business lines were even coded 1MB (one m b) service, one
metered business (line).
The history is clear and they've just reinvented the model for
internet but proactively enforced by technology rather than studying
your usage patterns or whatever they used to do, scan for business ads
using "residential" numbers, beyond bandwidth usage analysis.
And the CATV companies are trying to reinvent CATV pricing for
internet, turn Netflix (e.g.) into an analogue of HBO and other
premium CATV services.
What's so difficult to understand here?
